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.

Galvanized Steel Wire

AL FAISAL STEEL PRODUCTS CO. is famous for producing high-quality steel products, including galvanizing line end products. AL FAISAL STEEL PRODUCTS CO. is equipped with a modern, highly sophisticated 32 wire hot dip that has an automated galvanizing line with the facility for in-line Heat treatment (annealing) of drawn wire,and a nitrogen wiping facility for precision control of zinc coating film and consistency in the coating controlled by an automated Zinc Monitoring state-of-the-art facility.

Galvanized wire is a carbon steel wire coated with zinc. The two processes used to produce galvanized wire and coil are continuous hot dipping and electro-galvanizing. Generally speaking, the hot dip process consists of passing the steel through a bath of molten zinc. The electro-galvanizing process consists of the application of zinc by electrolytic deposition, or electroplating. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.

A zinc coating is one of the most effective and economical methods of protecting bare steel from harsh environments. The zinc not only serves as a barrier between the steel and the environment, it sacrifices itself to protect the underlying steel wire.Galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel from areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

Because we adhere to the highest production standards, our steel wire can resist abrasion, bending fatigue and crushing. We understand the importance of producing a high-quality product that must perform at an optimal level to maximize its service life. Our technical expertise ensures that our galvanizing steel wire products are manufactured to the highest standards in the industry.

The processing line has an automated zinc coating monitoring system that can control steel wire of sizes ranging from 0.8mm to 4.5mm, which are used in electrical cable manufacturing,fencing, construction, barbed wires, nails, tying and binding wire.The galvanized wires are always tested according to the customers’ requirements. Highly trained and qualified professionals using the latest equipment conduct testing around the clock.
