Frequently Asked Questions

Straight answers on K-Span roof panels, supply scope, custom sizes, and how Arch Span quotes practical steel canopy projects.

What do you supply for the fixed 4m × 6m panel option?

Roof panels only. Supports, posts, frames, foundations and fixings are separate unless quoted.

Do K-Span panels need rafters?

No. The curved panels lock together to form a self-supporting roof, then fix at the base to suitable supports, walls or containers.

Can you manufacture custom sizes?

Yes. Send your required width, length, delivery postcode, preferred steel thickness, and whether end walls are required.

What steel and finish do you use?

Hot-dip galvanised steel is commonly used. Panel thickness can range from 0.5 mm to 1.0 mm, with the final specification selected according to the span, location, loading and intended use.

Do you deliver across the UK?

Yes. We can arrange UK-wide delivery. Include your postcode when requesting a quote.
