Steel structure building is a new type of structure building system. The main steel frame is formed by connecting H-beams, Z-beams, and U-beams on the roof and walls by various panels.The steel structure building is sturdy and durable and can with stand high winds, snow, or earthquakes. Our structural engineers design the building structure according to the local wind and snow load to ensure that the entire building can withstand the harsh external weather.
The steel structure is installed quickly, and the construction time is short. All steel components were processed in the workshop, cut, welded, drilled, sandblasted, and painted, and delivered to the project site for installation. It does not cause environmental pollution at the installation site.
| The basic components of light steel structure | 1. Main rigid frame: composed of columns and beams;If there is a crane, a crane girder is also included. A, common materials: Q235, Q355; B. Common cross-sectional forms of beams and columns: H-shaped steel, trusses (beams are mostly used), lattice columns; C. Common structural forms: portal rigid frame, frame structure; 2. Support system: including tie rods, horizontal supports, inter-column supports, and corner supports. A. Tie rods are usually used: steel pipes, rectangular pipes;H-beam, channel steel, C-beam, angle iron and so on can also be used; B. The inter-column support is usually used: round steel, steel pipe, angle iron;H-beam, channel steel, I-beam, etc. can also be used; C. Angle braces are usually used: angle iron; 3. Enclosure system: including purlins, purlins rods, roof panels, wall panels, doors, windows, lighting panels, and gas floors. A. Purlin: mainly used, C-shaped steel and Z-shaped steel are cold-formed with hot-drawn steel plate and hot-rolled galvanized steel plate. B. Wall and roof color plates: mainly using high-strength, cold-rolled color steel plates, galvanized or aluminum-zinc color steel plates, stainless steel plates, aluminum alloy plates, and titanium alloy plates.Commonly used in China is galvanized or aluminum-zinc color steel plate. |
| Material classification | 1. According to the composition of the material: ordinary carbon steel (Q235) and ordinary low-alloy steel (Q355, Q390, Q420);Ordinary low-alloy steel is the addition of one or several alloying elements on the basis of ordinary carbon steel. 2. According to the intensity: Q235, Q355, Q390, Q420;Among them, Q235 and Q355 are commonly used materials. |
| Basic data for the design(depand on the project need) | 1. Dead load: must be provided 2. Live load: must be provided 3. Wind load: must be provided 4. Snow load: required in areas with snow 5. Ash load: it needs to be provided in dusty places (such as deserts and cement plants) 6. Crane load: lifting weight, number of cranes. 7. Seismic load: must be provided |
| The component connection method of the steel structure | 1. Welding connection 2. High-strength bolt connection 3. Rivet connection |
| Anti-corrosion method of steel components (commonly used) | 1. Galvanizing: 2. Spray anticorrosive paint: red dan, iron red, epoxy zinc-rich paint; |
| Advantages of steel structure | a) High strength; b) Good reliability; c) Easy to construct. |
| Features of lightweight steel structure |
Lightweight, accurate, convenient and fast molding, convenient for industrial production and transportation, construction and installation are more convenient, short construction period and low cost. |
