Looking to calculate the weight of L beam steel? Look no further than our comprehensive L beam steel weight calculator!
L-shaped steel, also known as angle steel, is a versatile and durable material used in a variety of large-scale construction projects, particularly in shipbuilding.
With its larger section coefficient and increased rigidity compared to flat steel profiles, L-shaped steel is an ideal choice for enhancing the storage capacity and economic efficiency of ships.
Our weight calculator allows you to easily determine the weight of your L beam steel based on its dimensions and allowable deviation specifications.
Whether you’re a professional metalworker or simply looking to complete a DIY project, our L beam steel weight calculator is the perfect tool for accurately determining the weight of your materials.
So why wait? Try our L beam steel weight calculator today and get started on your next project!
What is L-shaped steel?
L-shaped steel, commonly referred to as angle steel, is a new type of profile designed to meet the demands of large-scale ship construction.
When its height is the same as that of a flat steel profile, L-shaped steel has a larger section coefficient and greater rigidity compared to spherical flat steel.
Having a larger section coefficient increases the storage capacity of a ship and enhances its economic efficiency.
Furthermore, at the same section coefficient, the L-shaped steel panel is slightly thinner than spherical flat steel, which benefits the quality of welding.

Type of L beam steel
L-shaped steel is mainly categorized into two types: equal angle steel and unequal angle steel. The latter can further be divided into two subtypes: equal thickness on unequal sides and unequal thickness on unequal sides.
L Beam Steel (Angle Steel) Weight Calculator
As per the dimensional, shape, weight, and allowable deviation specifications of hot-rolled section steel (GB/T 706-2008), the length of hot-rolled L-beam steel is usually between 5m and 19m.
Typically, L-beam steel can be delivered based on either actual weight or theoretical weight in the market. The deviation between the theoretical weight and actual weight of the L-beam steel should not exceed ±5% to ±3%.
You can use the L beam steel weight calculator below to calculate the weight of the L beam steel.
