At Steel & Pipe Trading we stock structural tubing in round, rectangular and square shapes.
Structural tubing is a hollow section usually constructed from hot rolled metal coils. The coils are slit to the proper width for the section being manufactured and then formed into the final shape needed. Once the size is formed and the seams are welded together the tube is cut to the desired length to make a single piece of tubing.
Steel piping and tubing have a variety of uses in the automotive, plumbing, scaffolding, construction and manufacturing industries around Pietermaritzburg. Structural hollow sections are especially used in construction as they resist buckling loads more effectively than solid sections and have a high strength-to-mass ratio, bend strength and twisting stiffness.
Rectangular tubing, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular tubing have very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes them good choices for columns. They also have excellent resistance to torsion.
Tubing, which Steel and Pipe Trading stock, can also be used for beams as these have superior resistance to lateral torsional buckling.
The flat square surfaces of rectangular tubing can ease construction, and they are often preferred for architectural aesthetics in exposed structures
Square tubing is made the same way as pipe. During the manufacturing process flat steel plate is gradually changed in shape to become round where the edges are presented ready to weld. The edges are then welded together to form the “mother tube”. During the manufacturing process the mother tube goes through a series of shaping stands which form the round hollow tubing (mother tube) and then into the final square or rectangular shape.
Steel bar can be used for a wide range of applications, making it a cost-effective material solution for all types of commercial and industrial products.

Steel square bar
Mild Steel Square Bars are used in the building and fencing industry and a wide range of applications. With its high strength and versatility it can be drilled, welded and cut to suit your requirements.
Steel Flat Bar
Steel and Pipe Trading in PMB stock a broad range of steel bars with a width of 200 mm or less and thicker than 5 mm. Square and round bar are typically used to support light structures, while flat bar is usually used in fabrication.
We sell mild steel flat bar used for all applications including trellis doors, burglar proofing, grating, and engineering applications.
We stock a range of angle iron, also known as L-shaped at 90 degree angles. These are steel bars in the shape of an angle with equal or unequal sides. They are formed by bending a single piece of steel. Its 90° angled shape adds an abundance of strength and rigidity to numerous projects. This product is also easy to weld, cut, form and machine.These angles are used in a number of industries as braces to reinforce structures from the outside by increasing overall stress tolerance. Framing is the most common use for steel angles
but may also be used in sets of two or four to form the main parts of a building framework. Also used for brackets, trim and reinforcements. The larger the angle, the more weight and stress it can cope with.
Our stock in PMB includes a broad range of steel channels. Channels are constructed using a vertical web and top and bottom horizontal flanges with inside radius corners and is available in a variety of sizes and thicknesses. Channels are typically used as structural support along building frames for added reinforcement. They can be used for frames and braces machinery, vehicles, buildings and structural support applications. Use them for carports as support beams and in truck and trailer body building for reinforcement. Channels are also used in roof structures as trusses.
SHEETING in PMB
We can supply both Cold Reduced Sheets and Hot Rolled Sheets in various sizes to suit your commercial or domestic requirements.
Hot Rolled Steel Sheets
are the most economical steel sheets available for a wide variety of applications. Hot rolled sheets are produced at higher temperatures on rolling mills and generates a material that is resistant to work hardening and exhibits lower levels of deformation residual stress. Hot-rolling may leave surface imperfections such as scale or pits which require additional finishing for a smooth surface.
Products manufactured using hot rolled sheet include structural parts such as I-beams and H-beams, rails, stampings, automotive and equipment components.
These are easy to weld, form and drill, and have a slight grainy surface. HR Steel Sheet uses include: automotive panels, tool boxes, hoppers, drip pans, fuel tanks, trailer siding & roofing
Cold Rolled Steel Sheets
are rolled to a close thickness tolerance and possess a fine, smooth surface which can be painted . CRS Steel Sheets are easy to weld, form, drill. Parts that require crimping, bending, swaging and other types of cold forming are typically cold rolled. CRS Steel Sheet can be used for engineered products that require tight tolerances and coated surfaces: automotive and aircraft components, appliance industries, building frames, machinery parts, tool boxes, office furniture, tubing industries, hoppers, drip pans, fuel tanks, trailer siding
