FEATURES

Key Features and Optimal Roof Pitch Sheet Length for ST-39-700KL

1.Distinguished by a concealed-fix locking system between sheets and structure (BOLTLESS). Rib height of 39 mm and effective width of 700 mm (4 ribs per sheet) significantly increases rainwater discharge capacity, with pan stiffeners for added strength.
2.Suitable for roof pitches starting from 2° or 1:30, depending on sheet length and rainfall volume.
3.Purlins must be aligned level on a uniform plane to ensure unobstructed rainwater drainage; recommended purlin spacing should not exceed 1.30 meters, depending on sheet thickness.
4.Ideal for projects prioritizing high ribs, suitable for medium to large commercial and industrial buildings.
5.Supports natural spring curving (SPRUNG CURVED ROOFING) with a minimum convex radius of 50 meters, and machine crimp curving (CRIMP CURVED ROOFING) for barrel vaults and bullnose curves with a minimum convex radius of 500 mm.
6.Concealed clip-lock system (BOLTLESS) using connector clips secured with 65 mm and 16 mm screws on steel purlins.
