Seamless steel pipe is made of high quality carbon steel or alloy steel by hot rolled, cold rolled (drawing).

Micropiles are small diameter piles (typically 12” diameter or less) which can be installed in lieu of traditional piles. Micropiles capacities can range from 7 tons to 300 tons or more depending on the ground conditions, pile size, reinforcement and method of installation.

Manchette Valves and Button Valves can be supplied with the Mciropile tube or seperately supply.

Button Valves or with Manchette Valves can be supplied with the Microple tube or seperately supply.

Defferent sizes can be supplied for the wire hoop. We can also supply the goods according to the specific requirement.

Prestressing screw bars is rolled externally threaded in large diameter, high strength, high dimensional accuracy of straight bars. The bars can be connected at any cross section though coupling or screwed anchored.

ERW steel pipe is widely used in the transportation of oil and natural gas, but also can be used in industrial and civil buildings with structural steel pipe and pile steel pipe.

LSAW steel pipes are mainly used for oil, natural gas, water, steam, gas and other high, medium and low pressure fluid transportation pipeline and structure steel pipe, and undertook landmark project construction, the products are exported to Southeast Asia, the Middle East, Europe and America Countries, etc.

Double-sided submerged arc welding, not only has high penetration rate, but also has deep penetration ability, good weld quality, good compactness, smooth appearance of the weld, can meet the requirements of various properties of the weld. It can be used for the transportation of ordinary fluids such as oil, gas, water, and heating steam, and can be used for piling, structurem, etc.

Our Friction Bolt is a threaded anchor bolt system designed for underground engineering support. This Friction Bolts Mining support system is commonly used in underground mining, tunnels, and other engineering endeavors, offering robust geological support to prevent rock collapses and soil instability.

Mining cable bolt for roadway support under ground could be 19 wire pc strand , in the field of mine rock reinforcement  the Seale type structure is widely used  because of its high tensile strength and process easiness compare with traditional bolts. 

Wedge pins are used with flat tie to tighten adjoining concrete forms, securing the flat tie and concrete form in place.
