In the diverse world of construction, the Rectangular Hollow Section, or RHS, stands out as a masterpiece of structural efficiency. By combining the strength of a traditional beam with the clean, enclosed profile of a tube, RHS offers architects and builders a versatile solution for challenging designs. Its flat, symmetrical surfaces make it exceptionally easy to join and finish, providing a sleek look that complements both industrial and residential aesthetics.
We specialize in supplying high-grade rectangular sections that are engineered to provide maximum resistance to bending while remaining surprisingly lightweight. Whether you are framing a sophisticated glass facade or a heavy-duty floor system, our RHS products deliver the precision and reliability your project deserves.

Hangan Steel is a leading supplier of rectangular hollow sections melbourne builders rely on for superior strength and a professional finish. Often chosen for their “clean” look compared to open beams, RHS members are cold-formed and high-frequency induction welded. This process results in a structural member that is easy to weld, join, and paint.
As experts in RHS steel victoria, we ensure that our stock meets the stringent AS/NZS 1163 cold-formed structural steel pipe standards. Whether your project is domestic, commercial, or industrial, we provide the RHS steel sizes victoria required to satisfy your structural engineer’s specifications while maintaining a high level of aesthetic quality.
Selecting the right RHS section properties australia is critical for ensuring the load-bearing capacity of your frame. Below is a reference chart for common sizes available in the Melbourne market.
⚠ Always confirm final design values against certified manufacturer tables before structural design.

The flat faces of rectangular hollow sections melbourne make them more functional than circular pipes for many construction tasks. In structural steel RHS melbourne, we frequently see these sections used for:
RHS provides a flat surface for flooring materials to sit on while offering great spanning strength.
The clean edges and light weight make it ideal for high-end residential gate systems.
Used as the secondary framing members in industrial storage solutions.
Frequently specified for commercial staircases where a bold, geometric look is desired.
Many heavy-duty custom trailers in Victoria are built using RHS due to its high torsional stiffness (resistance to twisting).
At Hangan Steel, we go beyond simple supply. We offer specialized RHS fabrication victoria to ensure your steel is ready for immediate site integration.
Necessary for creating clean 45-degree corner joints for frames and trusses.
We weld steel caps to the ends of the RHS to prevent internal moisture buildup and corrosion.
Using our CNC equipment, we can punch or drill holes for bolts and services with absolute accuracy.
We supply galvanized RHS melbourne for outdoor use, as well as painted or powder-coated finishes for interior architectural projects.
When comparing structural steel RHS melbourne to Universal Beams or Channels, RHS offers several distinct advantages:
The smooth, enclosed profile is easier to clean and looks better when left exposed to view.
Hollow sections are much better at resisting twisting forces than open I-beams.
RHS often allows for a higher strength-to-weight ratio, which can reduce the cost of footings and transport.
The flat surfaces allow for simple “butt welds” or “fillet welds” without the complex cutting required for I-beams.
It is purely geometric. Rectangular hollow sections melbourne have different heights and widths (e.g., 100×50), whereas Square Hollow Sections (SHS) have equal sides (e.g., 100×100). RHS is usually better for beams, while SHS is often better for columns.
Yes. We supply galvanized RHS melbourne which is hot-dip galvanized or comes as a pre-galvanized product (like DuraGal). This is essential for preventing rust in Victoria’s variable climate.
Absolutely. It is the most popular choice for gates because it is strong enough to resist sagging but light enough for automatic gate motors to move easily.
