Steel Billets are hot rolled square bars produced by hot rolling continuous casting billets. Billets can be transformed into a variety of shapes and sizes after the processing stage and are often rectangular, circular or square shaped. Steel Billets are used in expulsion, fashioning, rolling and other metal-processing operations such as a raw material or feedstock. Rollco’s Billets are manufactured in accordance with the requirements of Australian Standard AS 1442/1022-1045.

Round Mild Steel bars are characterised by their circular cross section. Round Mild Steel has a smaller carbon quantity than other types of steel making it easier to cut, form, drill and machine. Round Mild Steel bars are often used as reinforcement and can be used in a wide variety of industrial, commercial and residential applications. Manufactured in Australia from 300PLUS steel, Rollco’s Round Mild Steel bars meet the relevant Australian and New Zealand standards of AS/NZS 3679.1 – 300.

Steel Angles are the most basic type of roll-formed steel and are formed by bending a single angle in a piece of steel, creating a ‘L’ shaped product. Equal Angles have two axes of the same length (equal) that create a 90-degree angle. Equal Angles are multi-purposed and are often used for reinforcement, framing, trims and brackets. They can be cut to any size and can be made in a range of strengths and thicknesses. The larger the steel angle, the more weight and stress it can bear. Equal Angles are manufactured in accordance with AS/NZS 3679.1.

Where the Equal Angle has two axes of the same length, Unequal Angles have two axes of different lengths (unequal) that create a 90-degree angle. The cross section has the same shape as an upper case ‘L’. Unequal Angles are often used in bridge building, reinforcements, framing and brackets and can be made in a range of thicknesses and strengths and can be cut to any size. Unequal Angles are manufactured in accordance with AS/NZS 3679.1.

Parallel Flange Channels (PFCs) are hot-rolled carbon steel channels sometimes referred to as ‘C sections’ or ‘C channel beams’ due to their shape. Constructed using a vertical web and top and bottom horizontal flanges with inside radius corners, the shape provides superior structural support, making Parallel Flange Channels an ideal product for frames and braces used for machinery, enclosures, vehicles, truss support beams, floor beams and portal frames. PFCs are available in a wide range of sizes and thicknesses.

Tapered Flange Beams are similar to the “𝚰” shape of Universal Beams, however they have tapered flanges – the two horizontal sections (flanges) taper, normally to a 98-degree angle from the web. Tapered Flange Beams are strong, as the flanges provide resistance to bending and are used regularly for support in residential and commercial construction projects as well as in industrial applications where maximal strength is paramount. Rollco’s stocks a range of Tapered Flange Beams in a variety of sizes and lengths, which are manufactured in Australia from 300PLUS steel and exceed the minimum requirements of AS/NZS 3679.1
