Complete roofs: measured, calculated and installed right

Building an industrial hall, a barn, a warehouse or a shed? Corrugated sheet metal is the fastest and cheapest roof covering for uninsulated buildings — and if you take it with dripstop (anti-condensation membrane), you avoid from the start the condensation dripping from the ceiling. We sell the full Bilka range, in any profile, thickness and colour.

What corrugated sheet metal is

Corrugated (or trapezoidal) sheet metal is a pre-painted steel sheet, folded into ribs that give it strength. It goes up quickly, covers large spans and costs less than tiles — which is why it is the first choice for industrial and agricultural buildings. From us you get it straight from the Bilka range, with everything needed: fixings, accessories, and the dripstop anti-condensation membrane if you want it.

The Bilka profiles — T18, T35, T45

  • T18 — low profile (18 mm rib). For facades and roofs with closely spaced supports. Clean, discreet look.
  • T35 — 35 mm rib, the most widely used. General use: industrial halls, warehouses, barns, sheds. A good balance between price and strength.
  • T45 — 45 mm rib, the strongest. For large spans and higher loads, where you want greater distances between supports.

All of them in thicknesses from 0.4 to 1.0 mm, matt or gloss, in any colour from the chart. You choose the thickness according to the span and how “stiff” you want the roof to be.

Dripstop — the sheet that does not drip

In uninsulated buildings, sheet metal condenses: the warm, humid air inside touches the cold sheet and turns into water that drips. Dripstop is a membrane bonded to the back of the sheet right at the factory — it absorbs the condensation like a sponge and holds it until it dries, instead of letting it drip onto fodder, animals or machinery. It comes ready to install and does not peel off over time.

Which buildings it is used for

Corrugated sheet metal, with or without dripstop, is the solution for:

  • Industrial and production halls
  • Warehouses and silos
  • Barns, animal shelters, farms
  • Sheds, machinery sheds, garages
  • Commercial buildings and logistics centres

For uninsulated buildings — where the sheet is directly exposed — dripstop pays for itself with the first batch of fodder that does not go mouldy.

Frequently asked questions

Which corrugated sheet profile should I choose — T18, T35 or T45?

T18 (18 mm rib) for facades and closely spaced supports; T35 (35 mm) for general use — industrial halls, warehouses, barns; T45 (45 mm) for large spans and higher loads. All in thicknesses from 0.4 to 1.0 mm.

What is corrugated sheet metal used for?

For uninsulated buildings: industrial halls, warehouses, silos, barns, farms, sheds, machinery sheds and logistics centres. It is the fastest and cheapest roof covering for this kind of construction.

Is corrugated sheet metal with dripstop worth it for an agricultural building?

Yes, on uninsulated buildings. Dripstop stops the condensation that would otherwise drip onto fodder, animals and machinery — it pays for itself with the first batch of fodder that does not go mouldy.
