[0002] Rebar is a type of steel that is relatively hard and has a certain degree of toughness. It is an almost essential material in today's construction industry. In large-scale construction projects, a large number of rebars of different lengths are often required. In order to complete the project within the specified time limit and speed up the progress of the project, engineers will build a rebar processing plant on site for centralized processing of rebar.

[0003] The steel bar processing plant provides an integrated closed functional space for steel bars from raw material storage to finished steel bar products and distribution. Most traditional steel bar processing plants are welded with steel structures such as portal steel frames and triangular roof trusses, some of which are connected by bolts, and the roof is a single-layer corrugated steel sheet roof.

[0004] Since construction projects need to be frequently transferred, self-built steel processing plants are generally only used for 2-3 years. Fixed buildings built by welding and cast-in-place methods are not suitable for the frequent mobility of self-built steel processing plants. After each demolition, the single-layer corrugated steel sheet roof becomes construction waste. Moreover, traditional steel processing plants use single-layer corrugated steel sheet roofs, which are airtight, stuffy, and hot indoors, seriously affecting the life safety of operators.
