Description:We primarily deal in a wide range of steel products, including color coated coils, color coated sheets, Baosteel color coated coils, galvanized coils, electro-galvanized coils, aluminum-zinc coated coils, colored aluminum coils, aluminum mirror coils, cold rolled coils, and hot rolled coils, sourced from major domestic steel mills. We maintain stable cooperative relationships with leading steel mills such as Baosteel, Maanshan Iron & Steel, Wuhan Iron & Steel, BHP Australia, POSCO from South Korea, and Yeh Hua from Taiwan.
Primarily used as the base material with electroplated zinc and cold-rolled steel, mainly for oil pans, automotive interior parts, etc.
Baosteel color coated steel coils offer superior decorative, formability, and corrosion resistance compared to other construction-grade panels. The coating has strong adhesion, maintaining a fresh appearance over time, making it an ideal alternative for building materials.
Baosteel's color coated steel sheet coating has a luster of 60° mirror finish, which is divided into low, medium, and high luster.
The coating hardness of Baosteel's color coated steel sheets is typically evaluated during testing with pencil hardness, or further tested for wear resistance and scratch resistance.
The coated types of Baosteel color coated steel coils are categorized as: Polyester PE, Silicon-modified Polyester SMP, High-Durability Polyester HDP, and Polyvinylidene Fluoride PVDF for differentiation.
Baosteel colored steel coil coating thickness: If the coated layer is one layer, the thickness is not less than 5μ; if the coating is two layers, the thickness is not less than 15μ.
Coating Structure: 1/1, 2/1, 2/2, 2/1M, 1/1 - One coat, one bake; 2/1 - Two coats, one bake (mainly used for producing colored coated sandwich panels); 2/2 - Two coats, two bake (mainly used for producing single boards).
2/1M - Two Coats One Flush (suitable for both single boards and sandwich panels)
Coating Colors: Select according to customer requirements (common colors include white and gray coated boards, sea blue coated steel coils, white coated boards, crimson coated steel coils, orange coated boards, deep soybean green coated steel coils, and brick red coated coils, etc.)
Coating Thickness: For polyester, the first coating thickness is typically 14um, while the second coating thickness is usually above 20um.
Coating Types: Polyester Resin (PE), Silicon-Modified Polyester Resin (SMP), and Polyvinylidene Fluoride (PVDF) Coating; Performance Features and Applications: PE boards have high corrosion resistance on their surfaces and edges, with a lifespan of generally 5-7 years, moderate decorative properties, suitable for steel structure roofs, walls, and structural components; SMP coated panels have better corrosion resistance than standard polyester, and are resistant to cut-through corrosion.
High performance, coating lifespan of about 10 years, moderate decorative value, suitable for structural building roofs, walls, components, steel windows, and automobiles; PVDF panels have excellent corrosion resistance, coating lifespan of 15-20 years, moderate decorative value, suitable for structural building roofs, walls, and components.
Waterway transportation services, ensuring timely and accurate delivery of goods to the customer.

Color-coated steel sandwich panels are ultra-light building boards composed of color-coated steel sheets as the facings and self-extinguishing polyurethane, polyisocyanurate, glass wool, or rock wool as the cores. They are bonded together using heat-curing adhesives under heat and pressure in a continuous molding process. These panels are characterized by their light weight, excellent thermal insulation, rapid construction speed, and vibrant colors. They are a new type of protective structure material that integrates load-bearing, thermal insulation, waterproofing, and decoration.


Color-coated steel sheets, also known as pre-painted coil, pre-painted metal coil, color steel, colored steel plate, coated steel plate, plastic composite steel plate, etc.
Coated steel coil, also known as color-coated steel coil, is a type of composite material/steel sheet that is sold in rolls or single sheets after being coated with paint or laminated with a polymer film. It is a product of the combination of metallurgy and chemical industries.


Proper selection of color coated steel should consider the natural and usage environment of the building, its design lifespan, and structural features to choose the appropriate steel type, specifications, coating, and finish. For architects, engineers, and processors, the focus is on the building's performance (impact resistance, seismic resistance, fire resistance, wind pressure resistance, snow resistance), residential performance (waterproofing, sound insulation, thermal insulation), durability (resistance to pollution, longevity, appearance retention), and competitiveness (cost-effectiveness, ease of processing, maintenance, and replacement).
Choosing the right color-coated steel sheet, coupled with appropriate corrugated steel design, can meet the building coefficient while reducing construction costs. The durability, processing properties, and appearance retention of the material are largely determined by the durability of the coating and plating.
Baosteel's Coated Steel Sheet Offerings - Specifications and Colors: 0.35-2.0mm Thickness
Width: 700-1550mm (Standard domestic board widths are typically: 1000mm, 1200mm, 914mm)
Color: Primarily chosen based on business preference and the match with the architecture and surrounding environment (common colors include: ocean blue, white gray, crimson, silver, silver gray, etc.)
The corrosion resistance of coated steel plates primarily depends on the structure of their metallic coating. Baosteel's color coated steel coil features a very tight and complex metallic coating structure, with the zinc-rich and aluminum-rich areas of the alloy coating interlocking, which enhances the corrosion resistance of Baosteel's coated steel sheets.
Our company owns a modern aluminum-zinc coated steel coil processing factory, capable of providing products as per customer requirements.
Steel Color Coated Sheet Processing (Custom Made/), Steel Coil Slitting, Cutting to Length, Semi-finished Product Processing, Punching, Coating Services. When selecting color steel coils, we often hear a word, thickness, which is also a key factor in purchasing color steel coils.
A crucial issue to note. Depending on different locations, the required thickness of color steel coils varies, so it's essential to understand the thickness of color steel coils before purchasing them.
