Made To Love: diy Faux Wooden Garage Door:Cold Rolled Commercial Quality Cold Rolled sheet is produced by processing Hot Rolled strip through a cold rolling process to obtain thinner gauges and enhanced surface finishes. Please contact us for further information on these products or any other products. Cold Rolled Drawing and Forming Qualities Similar to Cold Rolled commercial quality but possesses greater forming qualities. This product is utilised where yield and tensile strengths and elongation (ductibility) have to be guaranteed for its end use.

Domestic appliances, automotive parts, office appliances, steel furniture, etcgarage door opener repair charlotte nc Hot Rolled Steel Sheet – Commercial Qualitysliding door hardware bypass Hot Rolled steel coil is the most basic of steel sheet. sliding door company santa monicaIt is produced in coil form by the rolling of steel slabs at elevated temperatures through a hot strip mill where it is rolled down to the required finished thickness and re-coiled.garage door repair in fresno 1.5mm – 10mm (thicker on request) General engineering where moderate forming, bending and drawing are necessary

Hot Rolled Steel Sheet – Supraform EN10111 & DD14, Pickled and Oiled Supraform is a range of hot rolled structural steels with improved formability and weldability characteristics. The Supraform HR range relates to the minimum respective yield strengths of each grade. All the material is pickled and oiled. 1.6 mm – 5.0 mm (thicker on request) Automotive body and chassis components, any application where sharp bends are necessary, castors, etc. Hot Rolled – High Strength Steel Sheet with Low Alloy (Supraform TM range) Supraform TM is a range of high strength, low alloy structural hot rolled steel with improved formability. This Supraform range states with the specific TM number which illustrates the minimum yield strength of each grade. 2.0 mm – 10.0 mm depending on grade Automotive components, steel pipes for high pressure applications, mining equipment. Electrogalvanised steel sheet consists of a cold rolled steel substrate coated with Zinc by electrolytic deposition on a continuous line.

Coating can be applied on either one or both sides of the steel sheet. Its applications extends to forming, drawing, stretching and bending processes during manufacturing. The coating thickness can be controlled. The coated material is suitable for welding and painting. Further surface treatment may be added such as oiling, chrome rinse and phosphating. The zinc coating thickness can vary from 18gm² to 54gm² coated one or both sides of the steel sheet. Domestic appliances, Automotive components, steel furniture and air-conditioning, etc. EN10152 – DC06 (+ZE) Quality Range Equivalent to : Supradraw CR190 (IF) ZE, Hot Dipped Galvanised Steel Sheet Hot Dipped Galvanised steel is produced on a continuous Zinc coating line with either a Cold rolled or Hot rolled substrate. The product can be supplied with normal (regular), flattened minimised pangle or zero spangle finish. Coating may range from Z120 to Z450 coating (minimum coating 90gm² to 385gm²). Building applications e.g. garage doors;

– domestic appliances, air conditioner ducting, road signs, doors, Automotive components, general engineering. Commercial Quality, Lockforming Quality Colour Coated Steel Sheet This material is produced by coating the sheet with paint on a sophisticated coil painting line to the colour of choice. The substrate may be cold rolled, hot dipped galvanised, aluzinc or electrogalvanised material, depending which end application the material is required for. The sheet may be coated both sides with the chosen colour or coated one side with the chosen colour and the reverse side with a neutral colour epoxy primer. Variations to a flat sheet are available with various embossed patterns that are embossed on the material after manufacturing. Roof sheeting, paint pales, garage doors, domestic appliances(stoves and fridges), cold rooms, advertising sign boards, etc. Aluminium – Zinc Coated Steel (Aluzinc) Hot Dipped material where the coating constitutes of 55% aluminium, 43.4% Zinc and 1.6% silicon.

The great advantage of aluzinc is its superior corrosion resistance, attractive appearance and excellent thermal and light reflectivity. The coating thickness is typically 100gm² – 150gm². Roof sheeting, steel roof trusses, electrical switchboard cabinets, Structural sections, domestic appliances, refrigeration, air conditioner air ducting, light fittings, computer casings, electronic boxes, etc. Extra Deep Draw Quality This material is cold rolled steel coated with 100% hot dipped aluminium, coated both sides. This material has a very good corrosion resistance even in the presence of heat. This material offers a good thermal and light reflectivity and the product can be used in temperatures of up to 1100ºC. Coating thickness is typically 80 – 120gm². Bakery trays, Automotive exhaust systems, automotive heat shields, chimney ducts, construction profiles, heating boilers, air conditioners, tanks, etc. Extra Deep Drawing Quality Tinplate is produced from a single reduced cold rolled steel sheet which is electrolytically coated with tin.
