Cold rolled steel coils
Cold rolled steel coils are often used in the steel industry and are different from hot rolled coils. It refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole roll with a winder. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but generate more internal stress, and are often annealed after cold-rolling.

Product Description

The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.2.It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide,etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be producedaccording to user requirements. Rough surface, etc., to facilitate the processing of the next process.4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).5.High-speed rolling and full-continuous rolling can be realized with high productivity.

FAQ

Q1:What metal materials do you supply?
A:We supply one-stop full range of metal materials: pure copper & brass, carbon steel, hot-dip galvanized steel, PPGI/PPGL color coated steel, 201/304/316 stainless steel, high temperature alloy, industrial aluminum profiles and various structural profiles. Sheets, coils, tubes, bars are all available for infrastructure, new energy, machinery, chemical and electrical industries.

 

Q2:Can you customize material grades, thickness and sizes?
A:Customization is available. For stainless steel, copper, aluminum, galvanized & color coated steel, thickness, width and length can be adjusted per ASTM & EN standards. Profiles can be cut to fixed length or custom moulded according to drawings. Special alloy materials can be ordered from steel mills.

 

Q3:What’s the difference between galvanized steel and color coated PPGI?
A:Galvanized steel only has zinc coating for basic anti-rust with lower cost, suitable for brackets, guardrails and load-bearing structures. PPGI is galvanized base with colored paint layer, anti-rust & decorative, widely used for factory roof/wall panels and equipment housings. Thick galvanized steel for rainy coastal areas, PPGI for decorative outdoor projects.

 

Q4:Do you have spot inventory? What’s your MOQ?
A:We own 10,000 tons standardized warehouse with spot carbon steel, stainless steel, galvanized, copper and aluminum materials. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading with multiple metals is supported.

 

Q5:How long is the delivery time for spot goods & customized goods?
A:Spot goods can be loaded within 3-7 days; simple cutting processing orders take 7-10 days; mould opening & special alloy customization takes 15-30 days, subject to specific specifications.
