Manufacture of the profile steel elements for steel arch buildings
Load- bearing profile (JM200/615)
Load- baring parts of the steel arch buildings: side walls and roof are manufactured by roll-forming profile steel elements from steel sheets. The thickness of the material (S350) is 1.5mm. The height of the profile is 200 mm and useful width 615mm. Profile steel elements are typically 2-7 m in length and the holes for the joints (for stacking bolts M8) are pierced along both edges with 175mm intervals as well as the centre of the profile at the joins.
All stages of the manufacture: roll-forming, piercing, cutting and packaging are carried out by machine ensuring that the coating of the material is not unnecessarily damaged. Manufacture is fully automated which means that the parts are always dimensionally accurate and easily slot into place, rendering a test assembly at the factory unnecessary.
Following the roll-forming, parts such as the eave-, ridge- or roof elements then go through the bending process.
End wall profile (JM75/615)
End walls of the buildings are manufactured from a smaller profile measuring 75mm in height with a useful width of 615mm. This is also well-suited for manufacturing smaller buildings, such as storage yards. A separate range of these will be released at a later date.
The smaller profile can also be bent as well as pierced for joining holes. It is suitable for use as a load-bearing roofing sheet, for example. Thickness of the material is 0.7mm.
