The material has high strength and low weight. Steel possesses high strength and a high elastic modulus. Compared to concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, steel structures have smaller cross-sections, lighter weight, and are easy to transport and install, making them suitable for large spans, great heights, and heavy-duty structures.
The edging of a steel structure warehouse mainly includes gable wall edging, door and window edging, eave edging, and canopy edging. Among these, the sealing of door and window edging is particularly important, as leaks in steel structure factories often occur at the edging of doors and windows.
Last week, domestic steel market prices continued to decline sharply and accelerated, with the extent of the drop further widening. The price inversion for almost all steel varieties and specifications deepened increasingly. The transaction prices of upstream raw and fuel products began to loosen and fall, with the cash transaction price of steel billet products dropping below 4,700 yuan per ton.
