WELCOME TO TRIPLE S CO. LTD.
The pre-engineered steel frame of a pre-engineered steel building structure typically comprises more than 80 per cent of the pre-engineered steel building's weight. This 80 percent is an average and can vary plus or minus 10 per cent depending on the existence of mezzanines, crane runway pillars, type of panels used and the amount of construction accessories used in a house. For PEB Steel Structures, the unit of measurement is metric ton (MT). For a general average, the PEB Steel Structure weighs 25 kg by one square meter (1 m2). So one MT of PEB Steel Structure = 40 (1000/25) m2 of construction footage print.
The PEB Steel Structure consists of panels, secondary members and regular buyouts constructed from steel. PEB industry structures also apply to primary built-up & hot rolled participants. Constant depth or tapered depth built-up members typically account for more than 90% of the frame weight while the remaining 10% are usually accounted for hot rolled members. Secondary members in the PEB industry primarily apply to longitudinal roof and wall members which are roll shaped from galvanized coils or press broken from narrow galvanized sheets. This members' raw material is processed in five densities: 1.5, 1.75, 2.2, 2.25 and 2.5 mm.
