At Anping County Boli Hardware Wiremesh Products Factory, we have been a trusted manufacturer of industrial safety solutions since 1998. Our Industrial Blast Containment Cage is specifically engineered for chemical plants where explosive hazards demand robust protection. This cage is designed to safely contain and mitigate blast overpressures, protecting personnel and equipment while fully complying with OSHA standards. With over two decades of expertise and an annual export value exceeding US$5 million, we deliver products that meet rigorous global safety requirements.
Our blast containment cage is constructed from high-tensile steel wire mesh and reinforced structural frames, capable of withstanding extreme dynamic loads. It serves as a critical safety barrier in volatile environments, such as around pressure vessels, reactors, and storage tanks. The cage is engineered to absorb and redirect blast energy, preventing fragmentation and reducing the risk of secondary damage. Each unit is fabricated with precision welding and hot-dip galvanized or powder-coated finish for long-term corrosion resistance.
Key Features & Technical Specifications
- High-Strength Steel Mesh: Made from low-carbon steel wire with tensile strength ≥ 500 N/mm², available in mesh openings from 25mm to 100mm to balance visibility and containment.
- Reinforced Frame: Welded heavy-duty angle steel or H-beam base, designed to anchor securely to concrete foundations. Sizes customizable per client requirements.
- Blast Pressure Rating: Tested to withstand peak overpressures up to 10 psi (69 kPa) as per standard configurations; higher ratings available upon request.
- OSHA Compliance: Designed to meet OSHA 29 CFR 1910.119 and related process safety management standards, ensuring legal conformity in chemical facilities.
- Easy Installation: Modular panel design allows for rapid assembly and disassembly, reducing downtime during maintenance or relocation.
- Corrosion Protection: Hot-dip galvanized or polyester powder coating (optional) provides excellent resistance to harsh chemical environments.
- Ventilation Options: Integrated pressure relief panels or louvers can be added to control blast venting direction.
