Hot-rolled steel sheet piles mainly have three shapes: U-shaped steel sheet piles, Z-shaped steel sheet piles and linear steel sheet piles, as shown in Figure 1. Among them, Z-shaped steel sheet piles and linear steel sheet piles are relatively complicated in production, processing and installation. The price is 1/3 higher than that of U-shaped steel sheet piles.

Steel sheet pile construction adopts vibration pile sinking construction, erecting single-layer double-sided guide frames, and screen-type driving method to drive steel sheet piles.

Angle steel can be composed of various stress components according to different needs of the structure, and can also be used as a connector between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouses shelves etc.

Types of angle steel:mainly divided into two types: equilateral angle steel and unequal side angle steel, among which unequal side angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness.

Angle steel, commonly known as angle iron, is a long strip of steel whose two sides are perpendicular to each other and form an angle.

Rebar hot-rolled steel bar is followed by the English abbreviation of "hot-rolled ribbed steel bar" with the first letter of "fine" in English (Fine). Such as: HRBF335, HRBF400,HRBF500. Applicable grades for seismic structures with higher requirements:

Add E after the existing grades (for example: HRB400E, HRBF400E).

Steel Channel is a hot rolled, mild steel structural C shape with inside radius corners that is ideal for all structural applications, general fabrication, manufacturing and repairs. Steel Channel is widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, etc. It's C-shape or U-shape configuration is ideal for added strength and rigidity over steel angle when your project's load is vertical or horizontal.

H-shaped steel is a high-efficiency profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
