Weld-Free and Worry-Free: Redefining Structural Efficiency in High-Seismic Regions

-
图片
 For contractors weary of labor-intensive, time-consuming structural installations—especially in high-seismic zones— bolted steel framing offers a solution that radically redefines safety standards. Its core advantage? A design that guarantees ease of assembly without sacrificing seismic performance, streamlining on-site workflows while meeting every compliance requirement. The days of project delays caused by on-site welding, tedious alignments, or bulky reinforcement are over. Bolted steel components are prefabricated, precision-cut, and pre-drilled, ready for assembly straight off the truck. The intuitive bolting system requires no specialized skills for installation, allowing crews to erect frames with rapid precision, significantly cutting down installation time compared to rigid structures like concrete. No more worrying about mismatched parts or labor-heavy phases—this system is built for high-speed execution, even under the toughest site conditions. But simplicity doesn’t ...

Color Steel Composite Plate Various Plate Performance Introduction



Galvanised sheet

(1) Color coated plate

The base plate is hot galvanized or aluminized zinc plate, there is also the use of electro-galvanized base plate, surface paint by bending does not fall off.

For composite plate with colour steel plate is generally two coating a baking (two coating a), and two coating two baking (two coating two) or there are quality problems such as loose edge serious, middle loose heart, leakage of coating, large serrated edge, serious oval, uneven and so on can not be used for the production of composite plate.

(2) Galvanised sheet

Bad bonding effect is sometimes not very good and needs to be dealt with.

(3) Stainless steel plate

Good corrosion resistance, toughness is difficult to process; bonding effect is sometimes not good, need to deal with.

(4) Aluminium foil

Reinforced aluminium foil is a composite material with glass fibre reinforcement between aluminium foil and kraft paper, with functional characteristics such as fire retardant, fireproof, etc. It is also beautiful, durable and ideal for a new generation of heat insulation, thermal insulation and sound insulation.

(5) PVC

The main raw material of PVC foam board is polyvinyl chloride (PVC), which is characterised by a flat and beautiful surface, light weight, flame retardant, moisture resistant, sound insulation, corrosion resistant, easy to cut, good weather resistance, acid and alkali resistant and easy to clean.

(6) Trilaminate

Due to the limited length of each plywood, the compactness is not very good and the cracking phenomenon is difficult to solve.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

图片
  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

What are the differences between bolted ball grids and welded ball grids?

-
图片
 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...
