1. Hot-finished RHS:

 2. Cold-formed RHS: These are made by bending flat steel sheets into a desired shape and size without heating the material. They are processed in a series of steps that involves rolling, bending, and cutting, resulting in a lightweight and cost-effective product.

 3. Welded RHS:

 4.

 1. Hot-finished RHS: Higher strength, consistent quality, improved aesthetics, versatility, cost-effective

 2. Cold-formed RHS: Cost-effective,  versatile, light-weight, high strength-to-weight ratio, durable, sustainable

 3. Welded RHS: High strength,  Cost-effective, Easy to fabricate, Versatile,  Uniformity, Corrosion-resistant,  Aesthetically pleasing

 4. Seamless RHS: High strength, Corrosion resistance, Aesthetically pleasing, Easy to maintain,  Efficient use of space, Time-saving
