Express Pro roof sheets on purlins

Steel roof sheet system

A steel roof of our own Express Pro sheets: the standing seam Pro 75-400, the box profile Pro 32/1000 or the corrugated Pro 53, on Z or roll purlins at 1,200 mm centres. The structure is MET-PRO SFS at 600 mm centres, or a steel frame at 6 m bays with purlins between, with a liner sheet over it. Insulation between the purlins is optional. No sheathing board. Supply only, or supply and install.

Why specify our roof sheet system

Our standing seam, box profile or corrugated roof sheets on Z or roll purlins at 1,200 mm centres, over a liner sheet. No sheathing board.

  • Three roof sheets

    A standing seam that hides its fixings, a box profile or a corrugated sheet, each in 0.7 mm colour-coated steel.

  • On SFS or a steel frame

    MET-PRO SFS at 600 mm centres, or a steel frame at 6 m bays with purlins between.

  • Insulation when you need it

    Standard warehouses often go without it; larger commercial or factory buildings may need it.

  • A simple build-up

    A liner sheet over the structure, then Z or roll purlins at 1,200 mm centres under the roof sheet. No sheathing board.

The build-up

Inside to outside. Ask our technical team for the details for your project.

Roof sheet system FAQs

Which roof sheets go on this system?

Three of our Express Pro roof sheets: the standing seam Pro 75-400, the box profile Pro 32/1000 and the corrugated Pro 53.

Is there a liner sheet or a board?

A liner sheet, yes: it goes over the structure, under the insulation and the purlins. There is no sheathing board. Insulation between the purlins is optional.

Do I need insulation?

It depends on the building. Standard warehouses often go without it; larger commercial or factory buildings may need it.

What structure does it go on?

MET-PRO SFS at 600 mm centres, or a steel frame at 6 m bays with purlins between. The sheets go on Z or roll purlins at 1,200 mm centres.

Can I buy just the sheets?

Yes. Each roof sheet can be bought on its own, online at FAB Supplies, our group's shop, cut to length. For a project, send us the roof plan and we will price the sheets or the whole roof.
