Product Overview
Stainless Steel Press-Locked Grating is an engineered, high-precision metal grating manufactured by inserting cross bars into pre-slotted bearing bars under hydraulic pressure exceeding 500 tons. This mechanical pressure-locking process guarantees a permanent connection with zero welding marks, delivering structural integrity, dimensional stability, and a clean visual finish.
Fabricated from high-grade stainless steel-including SS304, SS316, and SS316L-this press-locked grating provides exceptional performance against chemical attack, saltwater spray, continuous moisture, and organic acids. It is a suitable flooring and architectural solution for marine environments, pharmaceutical cleanrooms, food processing plants, chemical facilities, and industrial infrastructure.
Key Advantages
Superior Corrosion Resistance and Material Integrity
• 100% Traceable Raw Materials: Every batch of raw material undergoes Positive Material Identification (PMI / XRF Spectrometry Testing) before production to ensure material accuracy.
• Grade Versatility:
SS304: General-purpose industrial application with excellent durability.
SS316 / SS316L: Low-carbon grades enriched with Molybdenum for superior resistance to pitting corrosion in chlorine, marine, and acidic environments.
Test Certificates: Orders can be dispatched with Mill Test Certificates (MTC) conforming to EN 10204 3.1 standards.
High-Precision Mechanical Press-Locking
• Precision Tolerances: Manufactured with strict dimensional controls (±0.5mm panel length/width tolerance).
• Zero Weld Flaws: Eliminates heat-affected zones, weld spatter, and discoloration, ensuring a uniform structural matrix capable of handling high static and dynamic loads.
• Heavy-Duty Applications: Engineered for high-load requirements, including equipment access areas and industrial maintenance decks.
Hygienic and Easy to Clean
The seamless mechanical joint design prevents deep crevices where dirt, moisture, and bacteria accumulate.
Complies with industrial sanitary requirements, making it simple to sanitize via high-pressure washdowns or chemical cleaning procedures.
Versatile Surface Finishes
• Mill Finish: Raw, durable industrial finish with natural oxide layers.
• Satin Finish: Reduced reflection and glare, providing an elegant finish for commercial walkways.
• Electropolished Finish: Smooth finish that removes surface impurities, maximizing corrosion resistance for cleanrooms and food facilities.

Corner Protectors: Reinforced edge guards prevent impact damage to panel edges during container loading and unloading.
FAQ
Q: What makes press-locked stainless steel grating better than welded steel grating?
A: Press-locked grating offers a cleaner surface without weld spatter, burning marks, or heat-affected weakness zones. It provides aesthetic uniformity, tighter tolerances, and smoother surfaces, making it suitable for architectural projects, cleanrooms, and food-grade facilities.
Q: How is the stainless steel material grade verified?
A: Raw material batches are inspected using a Portable XRF Spectrometer (PMI Test) upon arrival at the manufacturing facility. Mill Test Certificates (MTC EN 10204 3.1) are supplied with shipments upon request.
Q: Can custom shapes or cutouts be produced?
A: Yes. Custom manufacturing is available based on CAD or engineering drawings, including pre-cut circular, rectangular, or irregular shapes with perimeter banding.
