Angle steel is a hot-rolled structural section with two legs meeting at a right angle, forming an L-shaped cross-section. The profile provides stiffness in two directions and is a standard member for bracing, trusses, towers and connection details.
The 100x100 Equal Angle
A 100x100 mm equal angle has both legs 100 mm long and is a medium-heavy section widely used in building frames, lattice towers and industrial structures. The leg thickness is matched to the load, and the section properties are available from standard tables.
The same section can be specified to different standards. S235JR and S275JR to EN 10025 cover European structural service, A572 Grade 50 and Grade 60 to ASTM provide higher strength for US projects, A36 to ASTM is the general structural grade, and SS400 to JIS G3101 is the common Asian equivalent.
S235JR for general European building service.
S275JR for stronger members in EN projects.
A572 Gr50 and Gr60 for high-strength US specifications.
A36 for general US structural service.
SS400 for projects specified to JIS.
Bracing and wind bracing in steel frames.
Trusses and lattice girders.
Transmission towers and lattice masts.
Brackets, supports and connection details.
Each angle is verified for leg dimensions, thickness, straightness and surface condition, and the steel is tested for chemical composition and mechanical properties. Mill test certificates are provided with every delivery.
Select the grade by the project standard: S235JR or S275JR for EN, A36 or A572 for ASTM, and SS400 for JIS specifications.
Q: What is the difference between A572 Gr50 and Gr60?
Grade 60 has a higher minimum yield strength than Grade 50, allowing lighter sections for the same load.
Yes, hot-dip galvanizing is available for outdoor and corrosive service.
Standard lengths are 6 m and 12 m, with custom lengths cut to order.
Yes, mill test certificates are supplied with each order.
