We know that color steel tiles, when exposed to wind and sun for extended periods, will experience aging of the surface paint layer. This leads to the mentioned issue where oxygen in the air comes into direct contact with the base plate, causing rust. Therefore, the process of renovation and corrosion prevention is essentially about using paint to isolate the base plate from direct contact with the air, creating a completely sealed environment for the base plate. This prevents it from reacting with oxygen in the air, thereby achieving the goals of corrosion and rust prevention.
Water-based steel tile paint, environmentally friendly, non-flammable and non-explosive, resistant to aging and yellowing, water-resistant, maintains the surface color of the coated object against aging, retains vibrant colors, surface film highly resistant to aging, UV-resistant, paint film maintains normal performance at temperatures of 60-80°C, no issues at low temperatures down to -40°C, and no issues after 7x24 hours of water immersion, effectively extending service life by 6-10 years.
Updating and改造 of color steel tile roofs typically involves rust removal, sanding, polishing, and then applying anti-corrosion paint. However, traditional rust-proofing materials, due to environmental concerns and their pungent odor, can lead to significant air pollution. Additionally, they can increase labor costs and complicate construction difficulties.
The painted layer on the corrosion-resistant colored steel roof panels can undergo water-based anti-rust treatment and moisture-proof maintenance. Even if the roof is exposed to acidic or alkaline natural environments for a long time, the lifespan of the colored steel panels can still reach 5-10 years. The product's highlighted anti-rust treatment features are particularly effective for roofs with severe rust, showcasing remarkable results.

Reasons for regular renovation of color steel roof:
1. Due to rainfall and environmental factors, there may be some impact on the color steel roof, especially as it has been in use for a long time, leading to various degrees of rusting and corrosion.
2. Color steel sheet material contains a high iron content, which, upon contact with acids, alkalis, or organic solvents, can undergo a chemical reaction to form ferric oxide, commonly known as rust. Severe rusting of color steel sheets can lead to corrosion and the formation of perforated holes.
3. During rainy weather, the roof surface is affected by environmental elements and the oxidation decomposition of acidic and alkaline rainwater. The rain runs down the color steel sheets, leaving rust stains. Over time, the roof has developed extensive rusting areas.
If not promptly treated for corrosion and renovation, the corrosion of color steel plates will gradually worsen, even leading to holes, causing more severe leakage. By then, the repair will not only be corrosion and renovation but also require waterproofing and corrosion prevention for the entire roof, which will entail higher costs.
4. The roof's color steel sheets have good material, but most of the roof now has rust spots, with some areas being more severe. If not treated promptly for anti-corrosion and renovation to prevent further rusting, the longer the rusting goes on, the more likely the color steel sheets on the roof will develop rust holes, increasing the cost of repairs.
It is recommended to sand and remove rust from the roof as soon as possible, perform anti-corrosion renovation, and prevent re-oxidation and rust. After anti-corrosion treatment, not only is the color steel roof protected in a timely manner, but the lifespan of the roof panels is also extended, and the color steel roof is refreshed!
Color coated steel sheet waterborne anti-corrosion paint
1: Primarily used for the secondary renovation of steel structure color steel tiles, offering advantages such as simple construction, low cost, and long warranty period.
2: Pre-welding rust removal, followed by coating. Two coats of primer and topcoat are sufficient.
Waterproof and rust-proof renovation, no discoloration for five years, no cracking or peeling for eight years; Waterborne anti-corrosion paint for color steel tiles: First, clean the dust on the surface of the color steel tiles. Then, use an electric grinding wheel or wire brush, and sandpaper to grind the rust and oxides on the metal surface clean. Use a high-pressure water jet to rinse the floating dust on the metal surface clean. For oil stains, use gasoline or thinner to wipe. Pay special attention to rust removal at bolt connections and welds; the rust removal must reach ST2 level, completely exposing the metallic luster. Strengthen the metal roof without loosening, rust, dust, and perform anti-corrosion renovation when the roof is dry.
When using paint, it should be well mixed and can be applied once there is no color difference. The anticorrosion process for color steel roofing uses a two-coat method for application (one layer of anti-rust primer; two layers of finish paint), and the film should dry to a thickness of over 0.15mm.
The process of renovating color steel roofing is not as easy as one might imagine, but it can save a significant amount of costs, thus gaining popularity among people in real life.
Most applications of color steel roofing are outdoors, where they must withstand harsh weather conditions. Over time, surface corrosion and rust, as well as leaks, are inevitable. After prolonged use, considering a renovation of the color steel roofing is necessary to extend its lifespan. Using a water-based paint for the renovation is a good choice.
Color Steel Roofing Sheets, also known as colored corrugated sheets, are made by rolling and cold bending colored coated steel plates into various wave patterns. They are suitable for industrial and residential buildings, warehouses, special structures, large-span steel structures, and for roofing, walling, and interior/exterior decoration. They feature light weight, high strength, rich colors, easy installation, earthquake resistance, fire resistance, waterproofing, long lifespan, and low maintenance. Mainly used in industrial factories, self-built simple houses, containers, etc., they have been widely applied. Now let's discuss the construction process for the renovation of color steel roofing sheets.
Before repainting the color steel panels, the first thing you need to do is inspect the corrosion on the panels. If there is rust, it should be sanded first to more effectively remove rust from the corroded areas. It's recommended not to take shortcuts by using so-called rust inhibitors, as this practice does not yield as good results as proper sanding and rust removal.
After polishing is complete, dust and debris from the polishing process should be cleaned up.
Next, employ a high-pressure water gun to rinse off the surface, removing any residual rust and dust left from sanding, ensuring the board surface is clean, creating favorable conditions for the application of water-based paint for the renovation of steel roofing tiles.
After the surface water has dried, apply the color steel roof renovation undercoat. Once the undercoat is dry, apply the color steel roof renovation topcoat. Whether applying the undercoat or topcoat, mix the color steel roof renovation paint thoroughly before use. Ensure that the paint film is firmly adhered to the base material and between layers, without peeling or flaking; the dry film thickness of each paint layer meets the spraying requirements; the base surface is smooth, with no unevenness; there are no defects such as pinholes, runs, or sagging. This ensures a glossy, full paint film with uniform color and luster; the overall effect is harmonious and aesthetically pleasing.
Step 1: Roof Cleaning Services
Including roof screw replacement and reinforcement at loose panels, sand the area twice with a grinder, then clean thoroughly with high-pressure water, and inspect for roof leaks.
Step Two: Roof Waterproofing Construction
The panels are coated with a specialized waterproof base coat on both sides, then polyester fabric is applied followed by a waterproof top coat. Additional layer treatment is done around the roof structure, and the roof is inspected to ensure no leakage points.
Step Three: Overall Roof Coating with Base and Topcoat
The entire roof is coated with two layers of durable galvanized steel tile anti-rust primer, enhancing the corrosion resistance of the tiles. After complete drying, apply two layers of the same series CW310 custom anti-corrosion topcoat, providing excellent resistance to aging, high temperatures, corrosion, and acidity or alkalinity, thereby extending the lifespan of the roof.
Step 4: Apply primer and finish paint to the facade walls
After rust removal and cleaning with an angle grinder, the wall's waistline section and window surrounds are reinforced with two layers of glass fiber cloth and three coats of epoxy resin. The surface should be flat, without hollow spots or wrinkles, followed by a single coat of CW308 (thick paste) durable rust-preventive primer for colored steel tile renovation, and two coats of CW310 customized colored steel tile anti-corrosion topcoat.
Step 5: Conduct a comprehensive inspection of the roof
Ensure all roof areas are fully constructed and address any leaks or deficiencies.
Construction Plan
The coastal regions are primarily characterized by hilly and mountainous terrain, with a subtropical monsoon climate, warm and humid, classified as a humid area. Based on the climate and our understanding of the on-site conditions, we have initially determined the cause of the factory building's rust. Considering the installation of photovoltaic solar panels on the iron horse factory roof and the environmental requirements, which necessitate water and salt fog resistance, and heavy corrosion prevention, we have customized the renovation and corrosion prevention construction process for the factory's color steel panels. We recommend a high-performance corrosion prevention system solution. The project is proposed to use the CW series color steel panel renovation paint, ensuring long-lasting corrosion prevention after renovation.
Step 1: Roof Cleaning Process.
Including roof screw replacement and reinforcement at loose panels, sand the color steel tiles twice with our independently developed renovation and corrosion protection sanding machine, then clean them thoroughly with ultra-high-pressure water, check for roof leak points, and address leak repairs first.
Step Two: Apply rust-inhibiting primer and corrosion-resistant topcoat.
The entire roof is coated with one layer of CW series color steel tile renovation paint to enhance its corrosion resistance. After it is completely dry, apply two layers of custom gray, corrosion-resistant topcoat for the color steel tiles, providing the roof with excellent resistance to aging, high temperatures, corrosion, and acidic or alkaline substances, thus extending its lifespan.
Step Three: Identify and Fill Gaps.
Conduct a comprehensive inspection of the roof to ensure all areas are properly constructed.
A technical on-site survey of the surrounding environment and the factory warehouse has identified the main cause of roof rust as:
The region experiences a high humidity and rainy climate, making the roof prone to corrosion.
2. Workshop production grinding results in floating rust, and acid washing components produce corrosive gases upon heating.
3. The workshop is equipped with baking equipment, which generates high temperatures and causes corrosion to the roof.
4. No regular roof inspections are conducted. Necessary protective measures should be pre-planned.
We employ polishing and painting techniques, first thoroughly cleaning the base material, sanding off surface rust and flaking layers, allowing the primer to adhere well to the surface for rust and corrosion resistance. Post-sanding, the entire colored steel tile roof is subjected to high-pressure cleaning, utilizing high-pressure water jets from top to bottom to wash away rust particles and stains. A single coat of water-based colored steel tile specialized primer is applied, followed by two coats of acid and alkali-resistant, weather-resistant specialized topcoats once dried. The refurbished colored steel tile roof can be used for over 8 years.
