Tins coils are manufactured by winding wires around a core to create a wrapped helix pattern. They find their application in most electrical devices. We pride ourselves in producing high-purity uniform tin coils that feature the highest possible density for use in Semiconductor, Physical Vapor Deposition (PVD), and Chemical Vapor Deposition (CVD), processes including Atomic Layer Deposition (ALD), Thermal and Electron Beam (E-Beam) Evaporation, and more. Depending on your requirements, coils can be manufactured in various thicknesses and lengths with strict tolerances and alpha values for usage in gas detection and thermometry tolerances. Our offerings also include satin-coated coils, galvanized coils, prepainted coils, hot-rolled and cold-rolled coils, and more.

Slit coils are manufactured through a process called coil slitting. It involves a coil slitting line that cuts a master coil of metal into several narrower coils as it runs through a set of slitting knives. The continuous process is very precise, and it is, in fact, one of the best ways to cut metal compared to other processes. What’s more, depending on your requirements, the master coil can be broken down to your specifications. Choose any weight or width, and leave the rest to us. Leveraging the proper machines and expertise, we will get the job done right. Our slitting lines can also slit ferrous and non-ferrous metal, alongside advanced and ultra-high-strength steel and aluminum

Satin coated coils are covered with ZF coating that prevents metal oxidations. Hence, they are primarily used in the automotive industry and for external applications as they can resist corrosion up to 30 percent longer than cold-rolled steel. Furthermore, the coating permanently adheres to the metal, making it an ideal option for all-steel constructions and general machining and manufacturing tasks that demand long-term durability. Additionally, they are also easier to paint and feature a higher aesthetic standard. At RS Imperial Steel, we can supply satin-coated coils, satin-coated sheets, satin-coated slit coils, and satin-coated blanking.

Pre-painted steel coils are manufactured through a continuous coil coating process that comprises of cleaning, pre-treating, painting, and curing. Generally, the coils are painted with two-coat paint systems—first goes the primer, then a color coating is applied on the side meant for exterior exposure, whereas the reverse side receives a topcoat. Though cumbersome, the system results in the formation of uniform and aesthetically pleasing coils, and in turn, steel. Pre-painted steel coils are highly customizable. You can choose from several options like the metallic coating thickness, the types of top-coatings (acrylics, polyesters, silicone-polyesters, etc.), color, and treatments and primers. Pre-painted coil applications involve metal roofing, heating, and air conditioning parts, school buses, appliances, consumer electronics, garage doors, truck trailers, lighting fixtures, etc.

Galvanneal coils are manufactured by passing cold-rolled products through a molten bath of iron-zinc alloy that gives it a fine greyish matte finish. Perhaps, the primary advantage of galvanneal coils is that the galvanneal doesn’t flake off its coating when formed, stamped, or bent. Furthermore, the fine matte finish also helps the paint stick to the surface quite easily and is rust-proof. Galvanneal sheets also feature significant weldability, formability, paintability, and corrosion resistance. Hence, it is extensively used in electric equipment, automotive, signage, and other industries that demand good paintability with long-lasting service life. In addition, the galvannealed surface is ideal for both exposed and semi-exposed applications and can be painted before or after fabrication.

Electro-galvanized sheets are made by electroplating a pure zinc coating on one or both sides of carbon steel sheets. The resultant product has an exceptionally uniform thickness, in addition to the smooth and matte appearance, similar to the cold-rolled sheet. The surface quality makes it ideal for applications that require a high finish after painting, like in automotive exposed panels. Furthermore, the great control over coating thickness achieved with the electrolytic deposition process makes it ideal for improving forming and joining operations, particularly to get reliable results from automatic and robotic welding systems. Electro-galvanized coils are also readily paintable. At RS Imperial Steel, we can supply EG coils, EG Sheets, EG Slit Coils and EG Blanking.

Hot rolled steel products are classified into hot-rolled coils produced through hot rolling and hot rolled steel plates made by cutting hot rolled coils. The process of manufacturing hot-rolled coils involves a continuous casting system where the slabs are rolled, cooled, and coiled into the sizes required by the customers. Hot-rolled coils are heavily used in the automotive, agriculture, construction, automobile, and stamping industries.

Galvanized coils feature high resistance due to the zinc coating. As it prevents corrosion of metal under the influence of external factors without additional processing, it can be used in any climate. We are a reliable supplier of galvanized coils, galvanized sheets, galvanized slit coils and galvanized blanking. We pride ourselves in having a variety of quality product offerings and a wide range of services like slitting, cut to length, blanking, leveling etc. Perhaps, one of the important benefits of working with us is the reputable manufacturers we rely on and the timely deliveries.

Cold-rolled coils are essentially steel products made by cutting sheet-by-sheet plastic deformation of hot-rolled steel on cold-rolling mills. The main features of cold-rolled coils include accurate dimensional tolerances, enhanced mechanical properties, and better surface quality than hot-rolled sheets. Cold rolling also makes it possible to create thinner steel sheets that can’t be produced in hot-rolling mills. The main industries where cold-rolled coils are used include machine building, consumer goods, construction, automotive. When it comes to the construction industry, cold-rolled coils are mainly used to produce façade elements, steel structures, bent closed and open profiles, etc. Paired with consistent quality, our wide range offers opportunities for you to optimize both your products and processes.
