Rectangular Hollow Sections (RHS) are a smart choice for modern bridge construction, offering excellent strength-to-weight performance and high torsional stiffness. This article explains where RHS beams are used in bridges, how they support faster prefabrication and assembly, and what to consider for fatigue, corrosion protection and long-term maintenance.

Steel angle bars (angle iron) are a simple, strong solution for reinforcement, frames, brackets and edge protection. This guide explains equal vs unequal angles, common sizes and grades, finish options for corrosion resistance, and how to specify the right angle for your project.
