EN Standards (European Standards) constitute one of the most significant sets of technical specifications within the global engineering and construction sector. Specifically, the standard for steel angles—EN 10056-1:2017 (Structural steel equal and unequal angles — Part 1: Dimensions)—prescribes the nominal dimensions, tolerance requirements, and marking methods for hot-rolled eq...

With the continuous advancement of industrial technology, people have placed higher demands on steel. Steel plate is one of the four major types of steel (plate, pipe, profile, and wire) and a commonly used building material. So how much do we know about steel plates, and how are they classified? Steel plates are broadly classified according to their thickness, production method, characteristics, ...

ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon content makes it easy to be welded, machined as well as formed.

Precision alloy steel pipe is a special type of steel pipe characterized by high precision, high surface finish, and no oxide layer on either the inner or outer walls. It is typically produced using cold drawing or cold rolling processes, with extremely small tolerances for wall thickness and outer diameter.

ERW (Electric Resistance Welded) steel pipes are widely used in construction, water systems, scaffolding, and structural projects. One of the key reasons for their popularity is that ERW steel pipes are highly suitable for galvanizing, especially hot-dip galvanizing.

Stainless steel welded pipes are ubiquitous in petrochemical pipelines, cleanroom pipelines in food factories, and water supply systems in buildings. They have swept the market with their significantly lower price and high production capacity compared to seamless pipes, but the presence of weld seams has also sparked controversy regarding their reliability.
