一、輕型鋼結構的制造
輕型鋼結構的制造工藝與普通鋼結構并無很大的區別。輕型鋼結構的材料規格小，桿件細而薄，而且材料的調直、下料、彎曲成型、加工拼裝、構件的翻身搬運容易，不需要大型的專用設備，故特別適合在中、小型工廠加工制造。
圓鋼、小角鋼的輕型鋼結構桿件較細，容易成型，這是加工制造的有利條件。但在加工過程中也容易造成桿件彎曲和損傷等情況，這種彎曲和損傷對結構承載力的影響較大，加工制造時應加以注意。
采用冷彎薄壁型鋼結構比采用普通鋼結構一般多一道酸洗除銹或酸洗磷化處理工藝。當采用兩個槽鋼拼焊成方管時焊接量較大。由于桿件連接多為頂接，故下料的精確度要求稍高。過去人們曾擔心，冷彎薄壁型鋼構件的壁厚較薄，材料的調直不太容易，但實踐證明
First, the manufacture of light steel
Light steel structure of the manufacturing process and there is no great difference between ordinary steel. Light steel material specifications of a small, thin rods and thin, and the material straightening, cutting, bending, machining assembly, easy handling components turn over, no large-scale special equipment, are particularly suitable for small and medium sized factories processing.
Round, small angle light steel bars smaller, easier to shape, which is manufacturing advantage. However, in processing are likely to cause pole bending and damage, etc., that bend and damage the bearing capacity of the structure of large manufacturing should be paid attention.
Using cold-formed steel structure more general than the ordinary steel pickling descaling or pickling a phosphating treatment process. When using the two channel steel welded pipe welding Narikata large amount. As much as the top link bar connected, so the accuracy requirements under the material slightly. The past, people have worried that the wall thickness of cold-formed thin steel members, not easy to straighten the material, but proved
