Our window bars are manufactured to order, with a typical production lead time of approximately 4 weeks from order confirmation and final specification. This ensures each grille is built to the correct size, design, and security requirement.

Where hot-dip galvanising is specified for external installations, please allow an additional 1 week, bringing the total lead time to approximately 5 weeks. This extra process provides enhanced corrosion resistance and long-term durability.

Lead times may vary slightly depending on order volume, bespoke design requirements, or high-security specifications, such as LPS1175-rated window bars. We will always confirm accurate timescales at quotation stage to support your project programme.

The cost of window bars is typically very competitive, making them one of the most cost-effective physical security solutions for windows. Pricing will vary depending on size, bar specification, frame type, and finish.
