  Color steel plate Color steel plate , despite the double protection of galvanized layer and organic coating on the surface of the steel plate, if it is in a humid state for a long time, the water accumulated on the surface (including water produced by condensation in the air) will gradually infiltrate through the organic coating, thus causing corrosion of the zinc layer under the film of the organic coating, so attention must be paid to it when it is stored: (1) Not to be wet by water, stored indoors, avoiding open stacking. (2) The room should be dry and ventilated, without corrosive gases, and must avoid being placed in a place that is prone to condensation as well as the big temperature difference between cold and warm. Forced to temporarily store outdoors, underneath must have a square sleeper for cushion wood, and pay attention to good ventilation, choose flat ground, cushion wood above should also be horizontal, to make the steel plate stacked at the same height, to prevent...

  In steel structures , girders, rafters, and purlins are all structural components that play different roles in supporting the building's load and providing stability. Here's a breakdown of each: 1. Girder:     - A girder is a large horizontal beam that supports other beams or loads across an open space, such as a roof or floor.     - Girders are typically placed perpendicular to the beams they support and are designed to carry heavy loads over long spans.     - In steel construction, girders are often used in building frames and bridges to distribute loads from the beams to the columns or supports. 2. Rafter:     - A rafter is a sloped structural member that supports the roof covering and transfers its load to the walls or other supporting elements.     - Rafters are commonly used in roof framing to provide structural support and to create the pitched shape of the roof.     - In steel constr...
