Angle steel, also known as angle iron, is a long strip of steel with two sides perpendicular to each other at right angles. It is one of the common structural steel products. Although the names are different, angle steel and angle iron refer to the same material in practical applications.

When planning a steel construction project, selecting the right H Beam size and dimensions is essential for structural strength, cost estimation, and efficient material procurement. This comprehensive H Beam size chart and dimensions guide explains what each measurement means and provides standard H Beam sizes used in construction worldwide.

API SPEC 5CT is a technical specification standard for oilfield casing published by the American Petroleum Institute (API), primarily used in the oil and gas extraction industry. This standard specifies the steel grade system, chemical composition, mechanical properties, dimensional tolerances, and other technical indicators for casing and tubing.

ASTM A36 is the American standard for carbon structural steel plates, with the standard being ASTM A36/A36M-03a. This standard applies to riveted, bolted, and welded structures for bridges and buildings, as well as carbon steel sections, plates, and bars of general-purpose structural steel quality.

ASTM A513 carbon steel mechanical tubing is a versatile, high‑performance steel tubing solution widely used in commercial, industrial, and consumer applications.

Steel sheet pile are steel structures with interlocking devices on their edges, which can be freely combined to form a continuous and compact retaining or water-retaining wall. Cold-formed sheet piles are steel structures formed by continuous roll forming in a cold-bending unit, with continuous overlapping of the side interlocking joints to form a sheet pile wall.
