Topring Rollers was established in 1989 by Pieter and Dot du Toit after Pieter, a tradesman, was retrenched. The first piece of equipment the company purchased was a single Roundo Model R8 section rolling machine that was acquired at an auction and was in a serious state of disrepair. Since then the company has expanded to have over 30 section, plate and bending machines and is still operating from the same premises where it started and is now managed by Sean du Toit, the son of the founders.
But like many engineering disciplines they are defined by light, medium and heavy-duty. Most processors will cover most of these areas but a company manufacturing for example tankers and trailers will concentrate on their own requirements. Curved metal products can be found in homes, buildings, transport vehicles, stadiums and infrastructure developments. Whether you are looking for balustrading, staircases, roof trusses, flanges, drain pans, pipelines, heat exchangers or artwork you are more than likely going to approach a company that has section, angle or plate rolling capabilities.
We can bend most sections, in mild steel, stainless steel, aluminium as well as speciality steels. These include angle iron, flat bar, channels, beams, pipes, columns and rails. We can roll plates from 0.5mm down to small sizes, right up to 20mm over 3m lengths in mild steel and up to 16mm thick in stainless steel. Our press brake is used mainly for in-house applications, however, we are able to bend 3mm mild steel plate over 2.5m. We have more experience than anyone else in the country when it comes to rolling spiral sections. Our capacity is up to 219mm round tube, 300mm by 100mm channel and 305mm by 102mm beam. We are also capable of rolling up to 250mm by 30mm thick flat bars as spirals.
We have recently broadened our scope of capabilities. The newest addition to our shop floor is a Roundo Model 4R3S four roll section rolling machine, which has been supplied by Talmac Machine Tools. Roundo is originally a Swedish company but now is within the Faccin Group, a well-known Italian manufacturer of plate rolls and special rolling machines for larger diameters, thicker plates and challenging shapes.
The four roll machine is a fully CNC programmable section roller. The advantages of a CNC controlled four roll design over the more traditional three roll section rollers are that it is safer as the material is securely clamped in the pinch rolls from the start of the rolling process, there is less distortion as the material reforms in the pinch rolls on each pass, and it is also more efficient because the single operator and accurate repeatability due to the machine learning and the CNC programming capability.
