Steel Structure Rust-proof Waterproof Coating
Description
Technical Parameters
Leakage and rust of steel structure factories and color steel tile roofs are common pain points in industrial buildings. Ordinary waterproof coatings have no rust-proof function, while ordinary rust-proof paint has poor weather resistance and easy peeling. Steel structure rust-proof waterproof coating integrates waterproof, rust-proof and anti-corrosion functions to solve the two major problems of leakage and aging of metal roofs in one step. Our steel structure rust-proof waterproof coating takes high-elastic acrylic emulsion as the base material, mixed with composite anti-rust pigments and functional fillers. After film formation, it forms a dense physical barrier to block contact between water vapor, oxygen and steel substrate to fundamentally inhibit rust. Meanwhile, it forms continuous elastic waterproof film to seal leakage points such as plate joints and nail holes. It firmly adheres to color steel tiles, galvanized plates and section steel without peeling and blistering, with salt spray resistance over 500 hours and outdoor service life over 8 years. It has been verified in dozens of industrial plant and logistics park roof renovation projects with remarkable waterproof and rust-proof effects.
Traditional steel roof maintenance requires three processes: rust removal, primer brushing and waterproof coating, with long construction period and high labor cost and poor interlayer bonding leading to overall peeling easily. Our all-in-one coating reduces construction procedures by half and comprehensive cost by over 30%. It can be brushed, rolled or sprayed, with low technical requirements for workers. Old roof renovation does not require large-area demolition and short shutdown time with little impact on factory production. We can customize formulas with enhanced salt spray and acid-alkali resistance for coastal and industrial areas. For agents, this product has prominent differentiated selling points targeting core pain points of industrial buildings, easily penetrating plant maintenance markets with higher project profit margins than ordinary waterproof coatings.

Quality Control
Our quality control for steel structure rust-proof waterproof coating focuses on rust resistance and adhesion. Every batch of anti-rust pigments is tested for effective components to avoid replacing anti-rust materials with ordinary fillers. During production, dispersion fineness and emulsion ratio are strictly controlled to ensure uniform pigment dispersion and pinhole-free dense film after formation. Before delivery, finished products must pass adhesion, salt spray, artificial aging and water impermeability tests. Batches failing salt spray test will all be reworked. The factory has passed ISO9001 certification with regularly calibrated testing equipment and traceable data. We support on-site inspection by third-party institutions, and all delivered products come with complete inspection reports and certificates. With 12 years of production experience and strict quality control standards, every batch of products has stable and reliable performance.
After-Sales Service
We provide full-cycle supporting services for steel structure rust-proof waterproof coating. Pre-sales professional technicians match suitable models and construction schemes according to project rust degree and service environment, and provide free samples and technical consultation. Exclusive account managers track orders during sales, synchronize production and inspection photos, fully record container loading, and prepare customs clearance documents in advance to ensure intact and on-time delivery. After sales, we offer a 1-year warranty and provide remote guidance on base treatment, brushing and joint reinforcement during construction. If product quality problems occur, we will respond within 24 hours and propose solutions within 48 hours. We conduct regular project follow-ups to collect feedback and continuously optimize product performance and service experience.
Payment Terms
We adopt flexible payment policies adapted to capital rhythm of overseas purchasers. Conventional spot orders adopt 30% advance payment + 70% balance payment, with balance payable against copy of bill of lading to guarantee safe transactions. Orders with customized formulas and colors adopt 50% advance payment + 50% balance payment with weekly synchronization of production progress and controllable delivery schedules. US dollar T/T is supported, and letters of credit can be negotiated for large projects to reduce bilateral risks. Tiered quantity discounts are set for annual framework cooperation clients: higher annual purchase volume brings lower unit price, together with exclusive benefits such as priority production scheduling and free technical guidance. We adhere to win-win long-term cooperation and are willing to grow together with agents to jointly develop local markets.
