Steel Roofing 0.42mm BMT Corrugated (0.762 Coverage)

BRAND: Steeline

Not Available in your area

Tags:

A highly popular roofing choice, Steel Roofing 0.42mm BMT Corrugated (0.762 Coverage) is ultra strong and super lightweight. Made from light gauge, high tensile steel, it is able to span longer distances than most similar products.
Manufactured locally using quality ColorBond®; or ZinCalume®; steel, Steeline Corrugated is built to last.

Installation

Principle
Overlapped sheets of corrugated are to be fixed progressively along the building, in the opposite direction to the prevailing weather. This gives complete weather protection and a fast and efficient method of installing the roof. Each sheet consists of an 'over rib' and an 'under rib' and when put together they form an anti-capillary drain, preventing water entry.

Preparation

Lift packs of corrugated onto the roof frame, ensuring all sheets are the right way up, and with the over edge facing the end of the roof where laying is to commence. To prevent roof damage, walk on at least two ribs, and ensure your weight is evenly distributed as you walk across the supports. When the roof pitch is less than 25o or where there are extreme weather conditions, turn the sheet ends up approx. 80� at the high end and down approx. 15� at the gutter or low end. A shifting spanner can be used to do this.

End Lapping
When two or more sheets are required for full length cover, start laying at the gutter and work up to the ridge, then start the next run. The minimum end laps required are:
Roofs - Pitch up to 15� - 230mm
Roofs - Pitch over 15� - 150mm
Walls - 100mm

End laps in roofs with a pitch of <5 (1 in 12) are to be sealed. End laps must be positioned over a support and the support spacing on either side is to be those recommended for an end span.

Fixing

Recommended Fasteners
Steel framing (up to 5mm):

  1. Crest fixed - No 12x35 or a 14x42 hex head self drilling tek with neo washer.
  2. Valley fixed - No 10x16 hex head self drilling tek with neo washer.
  3. A s screw manufacturers have further developed their products, you can now use a combination screw that will screw into timber or metal depending on the thickness. Ask your Steeline member for a recommended fixing screw to suit your purpose.

Timber Framing:

  1. Crest fixed - No 12x50 or a 14x50 hex head type 17 self drilling wood screw with neo washer.
  2. Valley fixed - No 12x25 hex head type 17 self drilling wood screw with neo washer.
  3. As screw manufacturers have further developed their products, you can now use a combination screw that will screw into timber or metal depending on the thickness. Ask your Steeline member for a recommended fixing screw to suit your purpose.

Side Lap Fasteners
Side lap fasteners are to be added at the midspans of the sheets to lend support where spacings are over 900mm for roofs and 1200mm for walls, to ensure weatherproofing. Use No 8x12 hex head type 5 self drilling screw with neo washer or blind rivets.

Methods of Fixing

Roofs - Pierce fix through crests only using 3 fasteners/sheet or 5 fasteners/sheet depending on the location. At the end of sheets 5 fasteners/sheet must be used. Walls - Pierce fix through crests or valleys. 3 fasteners/sheet or 5 fasteners/sheet can be used depending on location. At the ends of sheets 5 fasteners/sheet must be used. If valley fastening is used side lap fasteners must be added beside each main fastener.

Precautions

When unloading bundles of sheeting with a crane always use a spreader bar and fabric slings to prevent damage. When manually handling sheets use clean dry gloves and do not drag sheets over each other. Storage of sheets should be above ground and under cover. Crest fasteners must not be over-tightened but driven in until slight deformation of the rib is observed and the neoprene washer is fully sealed.

Do not locate fasteners less than 25mm from the end sheets. Do not use punches to form holes for fasteners. Holes are to be drilled or self drilling fasteners are to be used.

Coverage

Steeline Corrugated has an effective coverage of 762mm when laps of 1.5 ribs are used.

Roof Pitch

Corrugated is designed so that sheets are to be overlapped by a minimum of 1.5 ribs to ensure the water-proofness. The minimum recommended roof pitch is 5.
