Our Agricultural Folding Doors provide an innovative solution for securing farm buildings with a durable, weatherproof folding mechanism. These doors are designed for agricultural use, offering full-width access for machinery while protecting livestock and crops from the elements. With a robust yet lightweight construction, they fold open easily and are ideal for barns, workshops, stables, and storage sheds. In this product page, we introduce the features and benefits of our folding barn doors, how they work, and why they’re a smart alternative to traditional roller shutters for many farm applications.
Agricultural folding doors are large barn doors made of high-strength fabric panels that open by folding rather than rolling. Each door consists of a flexible PVC curtain held in vertical tracks (or mounted to existing barn columns) that folds horizontally as it lifts. When closed, the door provides a secure, weatherproof barrier across the full height and width of the opening. When opened, the fabric panels concertina near the top, allowing almost the entire doorway to be clear for access. This design combines the protection of a traditional door with the ventilation of a mesh screen, making it perfect for agricultural buildings.
How it Works: As shown in the example barn, the folding door’s heavy-duty curtain rises and folds into pleats at the top of the opening. The door operates on a simple manual pull or winch system – you can open it by hand, and it remains stable even in high winds. No bulky drum or ceiling tracks are required; the door collapses neatly within the doorway itself. (An electric motor can also be added for push-button operation on larger installations.) The door is guided by side rails or existing steel/wooden columns, ensuring smooth opening and closing without swinging outwards. A small pelmet (hood cover) is used at the top to protect the folded curtain and prevent wear against the building façade
Full-Width Access: Unlike sectional or sliding doors that might obstruct part of the entrance, our folding doors fully clear the opening when open. They accommodate large openings up to 20 metres wide for maximum convenience, easily allowing tractors, loaders, and tipping trailers to pass through. Even extremely wide bays (up to 20m) can be spanned by this system.
Folding doors are an excellent choice for buildings with limited headroom or narrow bays. Because the door folds within the opening, you don’t need a tall space above the lintel to house a roll-up drum or overhead tracks. Only a small portion of the opening’s height is occupied by the folded material when the door is fully open (approximately 20% of the opening height). This means even low-eave barns can have a large door without major structural alterations. (By contrast, standard roller shutters require space for a barrel and canopy above the door.) The bi-fold design is a great solution for limited headroom situations.
These doors are purpose-built for agriculture, providing reliable weatherproofing while still allowing airflow. The curtain material is fully waterproof and wind-resistant, shielding your building interior from rain, snow, and drafts. At the same time, optional mesh or vented panels can be incorporated to maintain ventilation for livestock health. This balance of protection and airflow helps keep bedding dry and animals comfortable. In high winds, the flexible door is easier to operate and less prone to damage than rigid steel doors.
Agricultural folding doors are designed for simple, manual operation – you can fold and unfold the door by hand via a rope pull or crank handle. The lightweight fabric and folding mechanism make it easier to open than heavy steel roller shutters. For added convenience, electric drive units are available (single-phase or three-phase motors) that automate the opening, useful for very large doors or frequent use. You can even add remote controls for one-touch opening and closing. In either case, the door’s design ensures quick access without strenuous effort.
Our folding doors are built to last in tough farm environments. The curtain is made from industrial-grade PVC-coated fabric that is tear-resistant, UV-stable, and flame-retardant. This material won’t rot or rust and is proven to withstand years of outdoor exposure. The supporting hardware (tracks, guides, and fixings) are typically galvanized or stainless steel to resist corrosion. The system is designed to flex rather than dent if knocked, and any fabric panels can be replaced individually if ever damaged. Many agricultural folding doors come with a 10-year manufacturer’s warranty as a testament to their durability, ensuring long-term peace of mind.
When closed, the door provides full-height and full-width coverage of your opening, with tight seals at the sides and bottom to keep out rain and pests. This full-height protection is ideal for grain and feed stores – it prevents birds and rodents from entering, helping you meet farm assurance standards for crop storage. The optional pelmet cover at the top also improves weather resistance by shielding the folded section and preventing water ingress.
Our Agricultural Folding Doors are supplied in a kit form for cost-effective self-installation. They are engineered to mount onto existing structures – if your barn has steel RSJ columns or timber posts at the opening, the door tracks and brackets can bolt directly on. This makes installation straightforward and often eliminates the need for extensive building modifications. All necessary hardware, fabric, and instructions are included, allowing farmers or local contractors to install the door with basic tools. (Professional installation is also available if preferred.)
These folding doors are extremely versatile and suited to many agricultural applications. They were originally designed for multi-purpose use on farms, so you can use them on livestock barns, commodity sheds, machinery workshops, garages, stables, and general storage buildings. The design is especially beneficial for feed and silage storage bunkers or grain stores, where large open fronts need covering. Unlike heavy roller shutters, a folding door can be easily opened daily to provide ventilation in livestock housing, then closed at night for weather protection. It’s also ideal for smaller farm buildings where a traditional roller door might be overkill – e.g. closing off calf pens, poultry sheds, or stable blocks to prevent drafts.
Agricultural folding doors offer several advantages over conventional roller shutter doors in the right scenarios. First, no bulky overhead barrel is needed, which is great for low-clearance buildings or where roof space is used for lights or equipment. The folding mechanism also tolerates wind well – it doesn’t slam down or get stuck as easily as a rigid door might in a gale. Additionally, folding doors provide better airflow when partially opened, whereas solid roller doors would block ventilation entirely unless fully open. Maintenance is simpler too: with fewer moving parts and a rust-free curtain, there are less components to service compared to roller shutters with springs, drums, and numerous slats. Finally, our folding door can cover irregular or extra-wide openings (up to 20m) more easily than custom-building a roller shutter of that size. For narrow bays separated by internal posts, you can install multiple folding door sections, gaining flexibility that some one-piece roller doors cannot offer. In short, if your building has tight headroom or unique sizing, a folding door is often the more practical and user-friendly choice.
Our Agricultural Folding Doors are recommended for a wide range of farm and equestrian settings, especially where moderate opening sizes and frequent access are factors. Common use cases include:
Ideal for small to mid-sized livestock barns (dairy, beef, sheep, or goat sheds) where you need to keep out bad weather but maintain airflow. The folding door can replace traditional gates or wooden barn doors, giving a draft-free environment for animals while allowing easy passage for farmers and machinery.
Perfect for horse stable block entrances or indoor riding arenas, providing a weatherproof closure that also ventilates. The door can be kept closed in winter to prevent rain and cold winds in the stable aisle, yet opened quickly for bringing horses in and out.
For farm workshops, garages, or implement sheds, the folding door offers full-width vehicle access. Pull in tractors, ATVs, or equipment without the obstruction of center posts or half-width doors. When working inside, you can partially open the door to let in light and air without exposing the entire opening.
Highly suited for grain bins, feed storage barns, and silage pits that have large open fronts. The folding door keeps feed and grain dry and protected from birds/rodents. Its quick manual operation means you can easily open up during loading/unloading of grain or feeding, then secure the store afterward. The flame-retardant fabric is a safety bonus in feed stores.
In older farm buildings segmented into narrow bays or where multiple side-by-side openings exist, folding doors can be installed on each bay. Because they fold vertically, you don’t need adjacent wall space for a sliding door, and you avoid headroom issues that a sectional door might have. This makes them useful for retrofitting enclosed storage in traditional barns or cart sheds that have low beams and divider posts.
The portable nature of a folding door (bolted onto an existing frame) means it can even be used for seasonal structures. For instance, you can enclose a pole-barn during winter to store hay or straw, then fold the door up out of the way (or remove it entirely) during summer if full open access is needed. The self-fit kit design gives flexibility to adapt as farm needs change.
Our folding doors are engineered to perform in demanding agricultural conditions:
The door curtain is made from reinforced PVC/polyester fabric, similar to truck tarpaulins or industrial curtains. This material is 100% waterproof and UV-resistant, so it won’t degrade under sun exposure or constant rain. It also has a flame-retardant rating for safety, an important feature in hay barns and workshops. Despite being fabric, it’s incredibly tough – it can flex on impact (for example, if nudged by livestock or machinery) and then return to shape, unlike metal panels that might dent.
The supporting structure (guide rails, mounting brackets, hinges, and bolts) are made of galvanized or stainless steel, ensuring they won’t rust or corrode in the moist, ammonia-filled air of barns. The quality hardware provides stability to the door, keeping it taut against wind pressure. All components are designed for low maintenance – periodic checks and lubrication are usually all that’s required to keep the door running smoothly.
Agricultural Folding Doors are designed to withstand strong winds and daily use. The flexible nature of the door means wind loads are distributed; many farm fabric doors are rated for high wind classes. The door will flex rather than blow out, and it can be operated even in windy conditions without risk of the curtain whipping dangerously. If an accident occurs (e.g. a vehicle bumps the door), the damage is often minimal – the fabric might tear (which can be patched or panel-replaced), but the overall structure usually remains intact. Replacement fabric panels or repair kits are available to fix any wear and tear over time.
Thanks to the robust materials, these doors have a long service life. They are manufactured in the UK by specialists and undergo strict quality control. Many units in the field last well over a decade with minimal issues. For added assurance, the product typically comes with a comprehensive 10-year warranty against material defects. This warranty underlines the confidence in the door’s durability and the low long-term cost of ownership – a critical factor for farm budgets.
Agricultural Folding Doors are designed with farmers in mind, making daily operations simple:
The manual folding mechanism allows you to open even a large door in a matter of seconds. You simply release the catches and either push the door up or pull on the provided rope/chain to lift it. The door will fold and gather at the top. To close, you pull it down and secure the bottom anchors. There are no cumbersome bars to lift as with some older barn doors, and no need to slowly crank a roller shutter – it’s a swift motion to fold or unfold. This time-saving operation is ideal for busy farms where you may go in and out of the building multiple times a day.
If you prefer, you can equip the door with an electric motor drive from the start or later on. The motorized version allows push-button control, and can often be hooked to remote controls or even integrated with sensor systems (for example, to open when a vehicle approaches). We offer both single-phase (230V) motors for standard electricity supply and three-phase (400V) motors for heavy-duty usage. The motors come with limit switches and safety features to stop if an obstacle is detected. Automated folding doors bring convenience on par with modern garage doors, useful for larger installations or commercial farms.
Unlike complex roller shutter systems, folding doors have relatively few moving parts. There are no torsion springs that can break and no complex pulley systems – generally just the folding hinges and guide wheels. This simplicity leads to lower maintenance requirements. An annual check of bolts and occasional lubrication of the guide tracks is usually sufficient. The fabric is rot-proof and can be cleaned with a hose or pressure washer to remove dirt or cobwebs. In case any issues arise, spare parts (like replacement fabric panels, hinges, or motor parts) are readily available. Many farmers find that fabric folding doors are easier to fix themselves compared to metal doors, which might require specialist repairs if dented.
The door can be securely locked when closed, either with built-in locking bars or external padlocks, to prevent unauthorized entry. Because the door has some flexibility, it is also safer for people and animals – there are no rigid heavy panels that could cause injury if someone is accidentally in the way. If a power failure occurs on an automated door, manual override mechanisms allow you to still open or close it by hand. Additionally, the bottom edge of the door is soft, reducing risk of injury or vehicle damage if it were to contact an object. These safety considerations make folding doors a trusted choice for farms where both equipment and livestock need protection.
