Description

304 Stainless Steel Diamond‑Shaped Expanded Metal Mesh is a high‑performance metal product made by precision slitting and stretching of solid 304 stainless steel sheets. Unlike welded or woven mesh, it forms a one‑piece, seamless diamond structure with uniform openings, high structural integrity, excellent corrosion resistance, and long service life. It is widely used in architectural decoration, industrial filtration, safety protection, infrastructure, marine engineering, and environmental projects, providing a reliable solution for customers pursuing durability, ventilation, anti‑slip performance, and aesthetic effects.

Key Features

• Premium Material & Corrosion Resistance: Made of high‑quality 304 stainless steel, with excellent resistance to rust, oxidation, acid, alkali, and moisture. Suitable for indoor, outdoor, coastal, and mildly corrosive environments, with a service life of 15–30 years.
• High Structural Strength & Load Capacity: One‑piece stretching forms no welding joints, delivering 30–50% higher strength‑to‑weight ratio than traditional mesh. Tensile strength ≥520MPa, strong impact and pressure resistance, not easy to deform or break.
• Uniform Diamond Openings: CNC production ensures consistent hole size, smooth edges, good ventilation, light transmission, visibility, and anti‑slip performance, ideal for platforms, walkways, and barriers.
• Lightweight & Cost‑Effective: Lower material consumption than solid plates while maintaining rigidity, reducing transportation and installation costs; easy to cut, bend, and install.
• Stable Surface & Long Life: Natural metallic luster, can be brushed or mirror polished; no peeling or fading, low maintenance, suitable for long‑term outdoor use.
• Wide Adaptability: Resistant to high and low temperatures, fireproof, sound‑absorbing, and customizable for filtration, decoration, protection, and load‑bearing scenarios.

Applications

Customization Options
