It is a professional indoor high-standard structural material specially developed for dust-free, sterile, and aesthetic industrial spaces.
The core exclusive positioning of powder coated steel grating is modern clean indoor industrial grating. It abandons the outdoor anti-corrosion over-design of HDG grating, the low durability of liquid painted grating, and the underground damp positioning of bitumen grating. It focuses on three core performances: zero dust adhesion, easy water washing cleaning, and customizable high-grade appearance. The non-porous cured powder film completely isolates fine industrial particles, oil stains, and dry dust, maintaining long-term clean and tidy indoor industrial environments.
In global industrial engineering classification, powder coated steel grating belongs to high-standard indoor finishing structural grating, widely used in food-grade processing workshops, electronic dust-free assembly lines, pharmaceutical sterile laboratories, precision component testing workshops, and high-end factory indoor maintenance passages. It is the most cost-effective upgrade solution between ordinary painted grating and expensive stainless steel grating in clean industrial projects.
Manufacturing Process & Unique Powder Curing Protection Mechanism
The superior clean performance and durable surface stability of powder coated steel grating come from automated precision manufacturing and professional high-temperature curing process, forming a protective system that is completely different from all traditional grating coatings.
High-Rigidity Full Welded Carbon Steel Substrate
Adopt high-quality Q235/A36 industrial carbon steel as raw material. Through automated hydraulic resistance welding production line, longitudinal bearing bars and transverse cross bars form an integrated rigid rectangular grid structure. Full penetration welding ensures firm welding joints and uniform force dispersion. The standardized grid spacing maintains excellent ventilation and anti-fall performance, while ensuring stable medium static load capacity for indoor maintenance walking and light equipment placement, laying a solid structural foundation for clean industrial applications.
Strict Pre-Coating Dust-Free Pretreatment
Different from ordinary grating simple derusting treatment, powder coated grating implements full dust-free pretreatment. Including mechanical derusting, oil degreasing, oxide layer removal, and high-pressure dust cleaning, completely removing surface welding slag, floating rust, fine dust, and oil stains. The ultra-clean steel surface ensures zero impurity interference during powder adsorption and curing, avoiding particle bulge and coating unevenness, ensuring the flat and smooth finish of finished products.
Electrostatic Dry Powder Spraying & High-Temperature Curing
This is the core process that distinguishes powder coated grating from liquid painted grating. Adopt professional electrostatic spraying equipment to make dry powder particles uniformly adsorb on all surfaces, gaps, and welding seams of the grating through electrostatic principle, realizing 360° no-dead-angle coverage. Then put the grating into a constant-temperature curing oven for high-temperature baking, so that the powder particles melt, cross-link, and cure to form a dense, hard, non-porous integrated protective film, without solvent volatilization and paint sagging problems of liquid coating.
Physical Anti-Stain & Dust-Proof Protection Principle
The cured powder film has compact molecular structure and smooth non-porous surface, which fundamentally prevents fine dust, plastic particles, silicon powder, and industrial oil stains from penetrating and adhering. Compared with the porous surface of liquid paint that is easy to hide dirt, powder coating can keep the surface clean only by simple water washing. Meanwhile, the high-hardness cured layer has excellent scratch resistance, avoiding surface damage and dust accumulation caused by daily friction.
Finished Product Calibration & Cleanliness Inspection
After curing and natural cooling, all products undergo flatness calibration, surface flaw detection, and dust cleanliness inspection. Ensure uniform coating thickness, smooth matte finish, no particle protrusions, no peeling and cracking, meeting global food-grade and dust-free workshop industrial standards.
