Products Description
why choose our products
RHS steel pipe for Rectangular Hollow Section, which is a type of steel pipe. It is a closed structural steel tube with a square or rectangular cross-section. RHS is usually made from cold-formed steel, which is formed by rolling or pressing sheet metal into the desired shape. RHS is mainly used in the construction industry for mechanical and structural applications. It is a more economical structural solution for joining and different types of manufacturing work because of its flat surface. RHS is also sometimes preferred in structures with exposed structural supports for its aesthetic value. RHS is heat-resistant and weatherproof, and can withstand large variations in temperature. Hollow steel sections can withstand almost any extreme weather conditions, without compromising on their structural integrity.
SHS steel pipe stands for square hollow section, and is a type of structural steel tube with four equal sides. It has a flat surface that makes it easy to join and weld, with minimal edge preparation required. SHS is a middle-man between RHS and CHS in terms of attributes, appearance, and structural behavior. Hollow square pipes have many advantages, making them an ideal choice for construction projects. They offer strength, durability, and stability, are lightweight, require minimal maintenance, and offer sustainability advantage

Products Advantages
According to the section shape, it can be divided into RHS and SHS steel pipe, that is, steel tubes with equal or unequal side lengths. It is made of processed and rolled strip steel. Generally, the strip is disassembled, flattened, crimped, welded into a round tube, then rolled from the round tube into a square tube, and then cut into the required length. The main load bearing direction of the RHS and SHS steel pipe can be selected to be consistent with the deformation direction of the steel, so as to reduce the adverse effect of the anisotropy of the steel on the mold. Thermal conductivity is also one of the main performance indicators of mold steel, especially some hot work mold steel and plastic mold steel. The mold steel with good thermal conductivity can quickly transfer the heat generated in and from the work piece.

Differences Between RHS and SHS Pipes
| Feature | RHS (Rectangular Hollow Section) | SHS (Square Hollow Section) |
|---|---|---|
| Shape | Rectangular | Square |
| Strength | Higher load-bearing in one direction (long side) | Uniform strength in all directions |
| Applications | Frames, supports, beams | Columns, trusses, general structures |
| Aesthetic Use | Modern architectural designs | Symmetrical, clean look |
RHS vs. SHS vs. CHS (Circular Hollow Section)
| Type | Best For | Advantages |
|---|---|---|
| RHS | Directional strength (beams, supports) | Space-efficient, sleek appearance |
| SHS | Symmetrical structures (columns, frames) | Even load distribution |
| CHS | Aesthetic designs, fluid transport | No sharp edges, better pressure handling |
