We have a few customizing and selling pipelines for customers in the field of construction, road construction, bridge construction, public facilities, marine buildings and oil field construction. Our welded steel pipe products are installed by those who perform horizontal road drilling, directional drilling and piling procedures for these industries. We have two professional fields. The first includes the production of 20'dead zone stocks as steel sleeves, such as road sleeves, culverts, opening sleeves, open tunnel sleeves and well casing. The above picture shows 20 parts of our yard. The second includes customized steel pipe piling, such as foundation piles, bridge piles and ocean piling, including wharf piles, wharf piling and deep water pipe piles.

Steel casing pipe-bore casing

When soil and ground conditions are not suitable for supporting building structures, foundation piles are needed. Pipe piles are usually used for deep foundations to transfer structural loads to strong soil conditions in deep strata or deep underground. Southland PE & Super can cut and splice carbon steel piles with various diameters and wall thickness to meet the specific load requirements of these structures. We can also manufacture piling length of up to + or 93 feet and install boards, shoes or tapered points as required. We provide mechanical and cutting torch ends for "inclined x square" or "cant x slope". Our welders have passed the AWS D1.1 certification to meet the requirements of most marine piling, bridge piling or construction piles.

ASTM A500 tube is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. ASTM A500 is the most common specification in North America for Hollow Structural Sections (HSS). APPLICATIONS ASTM A500 applications include structural supports, building columns, highway signs, oil field services and communication towers.

CHARACTERISTICS A500 steel pipe can be subjected to most of the usual fabricating operations. Ductility is good. It bends well, flattens, cuts, punches, flares and flanges easily, and can be welded by the commonly-used techniques and practices. APPLICATIONS Common uses for ASTM A500 pipe include hand rails, posts, storage racks, displays, furniture, etc.
