Hubei Jingzhou pile driving steel casing steel plate rolling pipe processing manufacturer

Hubei Jingzhou pile driving steel casing steel plate rolling pipe processing manufacturerWe specialize in the research and development, production, and customized services of carbon steel large-diameter steel plate coils, relying on two major spiral steel pipe production bases and multiple automated production lines to deeply cultivate the fields of steel casing and steel plate coils. As a core supplier in the central and southern regions, the company adheres to the core concept of "quality first, technology driven", and its products are widely used in major projects such as bridges, high-speed railways, ports, and municipal engineering. It has become a strategic partner of China Construction Fifth Engineering Bureau, Changsha Metro and other units.

1. Material and Craftsmanship:

Made of high-quality Q235B/Q345B carbon steel, welded using double-sided submerged arc welding technology, with a weld strength of over 95% of the base metal. Support 6-24mm thick wall customization, with an outer diameter covering 630-2820mm and a maximum length of 14 meters, meeting the needs of ultra large diameter pile foundations.

2. Corrosion prevention and durability

We provide multi-layer anti-corrosion coatings such as epoxy coal tar, 3PE, TPEP, etc., which can improve corrosion resistance by 3-5 times and adapt to complex environments such as coastal areas and humidity. The surface is smooth without cracks, with a tolerance controlled within ± 1%, ensuring the accuracy of pile foundation construction.

3. Customized services

Support irregular machining such as conical, elliptical, and flange connections to meet special engineering requirements. 7-day fast delivery, equipped with a professional transportation team, covering regions such as Hunan, Hubei, Jiangxi, etc.
