Color steel plate, also known as color coated steel, is a high-performance composite material made of cold rolled steel, galvanized steel or aluminum zinc-plated steel as the substrate, after the surface chemical pretreatment, and then coated with organic coatings, and finally cured by high temperature baking. Its structure usually includes.
(1) Steel plate substrate: provides strength and stability.
(2) Zinc or aluminum zinc layer: to provide corrosion protection;
(3) Primer layer: enhances the bonding between the coating and the substrate;
(4) Top coat: to give color and beauty, and at the same time enhance the weather resistance.
Color steel plate not only has the strength and plasticity of steel, but also has the corrosion resistance and decorative properties of the coating, so it is widely used in various types of lightweight, durability and aesthetics of places with high requirements.
The base material of color steel plate mostly adopts galvanized or aluminum-zinc-plated steel plate, and the surface is covered with coatings of polyester (PE), high weathering-resistant polyester (HDP), fluorocarbon (PVDF), etc. Different coatings have different weathering-resistant properties. Different coatings have differentiated weather resistance.
-Ordinary polyester coating: weathering life 10-15 years, suitable for inland environment;
-Highly durable HDP coating: 20 years or more, suitable for industrial areas.
-PVDF coating: 25-30 years, especially suitable for coastal areas with high salt spray.
These coatings not only effectively resist the erosion of ultraviolet rays and acid rain, but also prevent the surface from cracking, blistering or discoloration, to ensure the lasting beauty of the building appearance.
Through roller coating technology can be customized with a variety of colors and textures (such as wood grain, stone grain), to meet the needs of modern architectural aesthetics. Shopping malls, gymnasiums often use color steel curtain wall, construction efficiency is more than 50% higher than traditional stone.
The thermal conductivity of sandwich color steel plate (filled with rock wool and polyurethane) is as low as 0.022W/(m-K) (data from China Building Materials Testing Center), which is suitable for cold storage, data centers, and other places with high requirements for temperature control.
color steel plate weight is only 1/30 of concrete structure, tensile strength can reach more than 550MPa, greatly reduce the building load, suitable for large-span steel structure plant.
- Factory roof/wall: single layer color steel plate thickness 0.4-1.2mm, span up to 12 meters without support.
- Logistics warehouse: rock wool sandwich color steel plate, up to fire B1 level (according to GB8624-2012), not only good heat preservation effect, but also effective flame retardant, in line with the safety standards of modern storage buildings.
color steel plate becomes the ideal material for public facilities because of its durability and decorative.
-Airport terminal: fluorocarbon coating color steel plate is anti-ultraviolet ray, pollution-resistant, easy to clean, and guarantees that the building facade is as new as new for a long time;
-Hospital partition: antibacterial coating color steel plate can effectively inhibit the growth of bacteria, to meet the clean demand of medical environment.
-Assembled houses and integrated houses: color steel plate houses adopt modular assembling method, the construction period is 60% shorter than traditional buildings, and it becomes the first choice for post-disaster reconstruction, construction site dormitory and temporary office.
-Indoor ceiling and partition: 0.3mm thick color aluminum plate is not only light and beautiful, but also has moisture-proof and fire-proof performance, which is commonly used in kitchen and bathroom ceiling.
-Rail transportation: high-speed rail, subway car internal structure often use lightweight color steel plate, in order to reduce the weight of the car, reduce energy consumption.
-Truck cargo box and container: wear-resistant color steel plate life is 3-5 times longer than ordinary steel plate, reducing maintenance frequency and improving transportation efficiency.
-Appliances shell: refrigerators, washing machines, air conditioners shell commonly used VCM coated color steel, not only to ensure corrosion resistance, but also to achieve a diverse range of design.
-New energy equipment: photovoltaic stent and wind power equipment shell widely used aluminum magnesium zinc color steel plate, its corrosion-resistant life of more than 25 years, to meet the long-term needs of the new energy industry.
Color steel plate is made of galvanized or alumina-zinc plated steel plate, with color coating on the surface, and its density is only 1/10 of traditional concrete, but its tensile strength can reach 300-500MPa (Data source: Dimension and Allowable Deviation of Cold-Rolled Steel Plate and Strip GB/T 708-2019), which is especially suitable for large-span building structure.
Through the double protection of plating and coating, the service life of color steel plate can reach 15-25 years in wet or acidic and alkaline environment. For example, the weather resistance of fluorocarbon coated color steel plate is more than 3 times higher than that of ordinary coating (refer to Color Coated Steel Plate and Steel Strip for Construction GB/T 12754-2019).
color steel plate can be prefabricated in factory and assembled on site, and the construction speed is 60%-70% faster than traditional building materials. Taking 1000 square meters workshop as an example, it takes only 3-5 days to complete the installation by using color steel plate roof.
Color steel plate can be 100% recycled, and its reflective heat insulation performance can reduce building energy consumption by about 20% (International Iron and Steel Association statistics). The thermal conductivity of some models is as low as 0.040W/(m-K), which is close to the standard of heat preservation material.
(1) Substrate and coating: Prefer aluminum-zinc-plated substrate or high zinc layer (e.g. Z275) products with better corrosion resistance.
(2) Coating type: choose the coating according to the environment, coastal areas recommended PVDF coating, inland dry areas can choose PE coating.
(3) Specification thickness: according to the architectural design to select the appropriate thickness, insufficient thickness can easily lead to insufficient strength.
(4) Brands and certifications: Choose the regular products in line with the national standard GB/T12754 or the European standard EN10169, to avoid low-quality panels.
color steel plate surface cleaning to maintain the appearance of clean workshop and environmental health is crucial. Regularly clean color steel plate surface can effectively remove dust, oil and other debris, improve the overall health level of clean workshop. It is recommended to use warm water and neutral detergent to clean the surface of color steel plate every once in a while, avoiding the use of acidic or alkaline cleaner to avoid damaging the surface coating.
Regularly check the sealing performance of the connection of color steel plate to ensure that there is no loosening or leakage in the connection. Especially in the process of workshop use, may be due to vibration or other reasons lead to loose connections, timely detection and repair can effectively avoid clean workshop air leakage, maintain cleanliness.
The anti-corrosion treatment of the surface of color steel plate is crucial, and coating or galvanization can be used to protect the color steel plate and prolong its service life. Regularly check the surface of color steel plate whether there is rust or corrosion phenomenon, such as timely repair or replacement to avoid further expansion of damage.
If the surface of color steel plate adopts special coating, such as fluorocarbon coating, etc., it is necessary to check the condition of the coating regularly and carry out necessary maintenance and repair. Timely repair of damage to the coating can protect the surface of the color steel plate and extend its service life.
The air outlet and exhaust port of the clean workshop is an important part to ensure the air circulation and quality. Regularly clean the air outlet and exhaust port to prevent the accumulation of dust or debris blockage, to ensure smooth air flow and improve the ventilation effect of the clean workshop.
The bracket and structure of color steel plate is an important part to support the whole clean workshop, and it needs to be checked regularly for its stability and safety. Timely discovery and treatment of problems such as loose stent or damaged structure can effectively guarantee the safe operation of the clean workshop.
