DC Series Gate

Our DC Series Gates are engineered for superior durability and security. Built with double steel channels riveted together, these gates are tough and reliable. Each gate features double rows of steel lattice bars, smoothly gliding on nylon bearings for effortless operation. The leading and trailing edges are reinforced with steel box-shaped sections for extra strength. Best of all, DC Series Gates can be custom-manufactured to fit almost any size, making them the perfect solution for securing your space with confidence.

Our EG Series Gates are designed to strike the perfect balance between security and affordability. With single steel channels alternating with flat steel bars, these gates are both strong and cost-effective. The single rows of steel lattice bars glide effortlessly on formed steel guides, ensuring smooth, hassle-free operation. Standard sizes go up to 30 feet wide and 12 feet high, but we can offer even larger dimensions for select models. Whether you need reliable security on a budget or a customized solution, EG Series Gates deliver.

Our LT Series Gates are crafted for those who demand top performance at an affordable price. Designed with diagonal steel lattice channels in a diamond pattern, these gates are lightweight yet durable, offering smooth, effortless operation thanks to nylon spacers. Ideal for budget-conscious buyers, the LT Series is available in widths up to 26 feet and a standard height of 6’6″. For cost-effective security that doesn’t compromise on quality, LT Series Gates are the perfect fit.

Our DC and LT Series Gates are also available in fully portable versions, mounted on rolling stands for maximum flexibility. Perfect for temporary use, these gates offer adjustable widths and extend to a typical height of 6’6″. Whether you need fast, reliable security on the go or a versatile barrier solution, our portable gates deliver convenience without sacrificing durability.

Keep your gates secure and out of sight with our custom Gate Cabinets. Designed to conceal gates when not in use, these recessed steel cabinets come with lockable hinged doors for added protection. Available in both deep and shallow designs, they can be tailored to fit various installation needs, offering a sleek and secure storage solution for any space.

NOTE: Most gates can be either single sliding or bi-parting, and can roll on floor casters or in top or bottom tracks.

Our Chain Gates are crafted with horizontal and vertical rows of interconnected chain links in a square pattern, suspended from a top track for smooth operation. Commonly used as collapsible sliding enclosures for truck trailers, these gates are easy to use and highly adaptable. They also provide an affordable access control solution for smaller building openings, offering versatility and security without breaking the bank.
