The general sequence of welding is: pre welding inspection → preheating and rust removal → installing welding pads and arc plates → welding → inspecti

Components due to various accidents caused by deformation, distortion, disability, depression, etc., resulting in the weakening of component section,

It refers to the structural form of steel plate and hot-tied, cold-formed or welded profiles connected by connecting parts that can withstand and tran

The strength index of steel is determined by the elastic limit σ e. Yield limit σ y. And tensile limit σ u. The design is based on the yield strength

The processing and production of the steel structure of the equipment is similar to that of the precision steel structure, between the ordinary struct

Light steel structure In order to ensure the thermal insulation effect, the thermal insulation materials used in the external walls and roofs of build

It is composed of roof truss, structural OSB panel, waterproof layer, light roof tile (metal or asphalt tile) and related connecting parts.

The upstream of steel structure is mainly the steel industry, and the price fluctuation of steel products directly affects the procurement cost of the

Although China had outstanding achievements in iron structure in the early days, it remained at the level of iron buildings for a long time. Until the

Steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low.

Steel is characterized by high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for
