Billets

A billet is a length of metal that has a round or square cross-section, Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. Billets are further processed via profile rolling and drawing. Final products include bar stock and wire.

Centrifugal casting is also used to produce short circular tubes as billets, usually to achieve a precise metallurgical structure. They are commonly used as cylinder sleeves where the inner and outer diameters are ground and machined to length. Because their size is not modified significantly, they are not always classified as semi-finished casting products. 

I.    Billet Size   : 150 X 150mm and 130 X 130mm
II.   Grade         :  ASTM A 615, SASO SSA 2, BS 4449, SAE 1006, SAE 1008, SAE 1010,
                          SAE 1012 and other grades as per customer specifications.

Cold Drawn Wire

The Wire Drawing Division of AL FAISAL STEEL PRODUCTS CO. has the world’s best wire drawing machines, which include advanced features. AL FAISAL STEEL PRODUCTS CO.’s international experience and knowledge have helped significantly expand its product range and manufacturing capabilities in recent years. One of these improvements is the introduction of in-line inspection using laser detection diameter measurements and pressure sensors with a PLC mechanism.

The drawing instruments are carefully designed to guarantee optimal quality in the production process. This includes:

  • Uniform coil weight
  • Traceability of coils

Cold drawn wires are manufactured according to ASTM and DIN standards from Low carbon and High carbon steel for diverse applications in the relevant industries. Wire rod is a Hot Rolled product that is usually annealed, pickled or surface treated. What is most important here is the processing of the wire rod using cold forming or drawing. This allows the production of an enormous variety of end products. These include:

1. Spring wires for general engineering

2. Spring wires for mattresses
