Robust Protection for Commercial & Industrial Property
Security is only as strong as its weakest weld. No. Twelve Welding Company provides specialized security fabrication and facility maintenance services designed to protect your physical assets and ensure the safety of your personnel.

Security & Maintenance Specialties

Perimeter Defence
Gates & Enclosures: A weak or compromised gate is a security liability. No. Twelve specializes in the repair and reinforcement of commercial gates and steel fencing. We ensure hinges are heavy-duty, latching mechanisms are precise, and the structural integrity of your perimeter is restored.
Asset Fortification
Container Modifications: Shipping containers are often the target of site theft. We provide “Fortification Packages” that include welded-on lock boxes and reinforced door frames. We can also modify containers for specific industrial uses, including venting, custom doors, and internal structural racking.
