q345 steel is a commonly used structural steel in China, and its standard is GB/T 1591-2008 "Technical Conditions for High Strength and low alloy Structural Steel".
Steel structure includes housing steel structure, bridge, tower mast, container and hydraulic structure and other fields. Now only a brief description of housing steel structure sixty years of development.
Al-Mg-Mn alloy building sheet, the use of German DIN1725 designated in the label 3004 aluminum alloy, Al-Mg-Mn alloy building sheet substrate thickness is generally used 0.7-1.2mm, its highly cost-effective roofing, exterior wall material aluminum alloy has been widely used in the construction industry.
Purlins, also known as trusses, are actually roof beams that are perpendicular to the roof truss and used to support the roofing material, in order to reduce the span of the cabin panels and secure the roof panels.
