Bidirectional Composite Strengthening Systems

Gateway Composites LLC offers multiple standard fabric styles and constructions as well as custom design and manufacturing capabilities to meet your specific application requirements. We offer woven and unidirectional carbon fiber fabrics incorporating a broad range of aerial weights, weave constructions, yarn inputs, warp/fill counts, widths and raw materials.

We provide field ready systems and kits (private labeling available) that include high performance epoxy resin and pre-cut carbon fiber fabric for efficient application and use in the repair, retrofit and reinforcement of concrete, wood and steel structure, including: tanks, bridges, parking garages, concrete/masonry buildings, tunnels, silos, piers, precast products, telecommunication towers, basement walls, patio and driveways.

Just how strong are Carbon Fiber Reinforced Polymers?

A customer covered a paint stick with CFRP. The result… strong enough to hold up a grown man. Imagine what CFRP can do for your degraded vessel that you don’t have the time or resources to completely replace right now.

Structural Restorations using Carbon Fiber-Reinforced Plastics (CFRP)

Gateway Composites carbon fiber fabric systems are designed specifically for structural strengthening applications on structures that have seen the harshest of corrosions. They are available in various weights, weaves and directionals of fabric to optimize the structural design. When you pair Gateway Composites CFRP with one of our tank lining systems, your vessel can be restored to its original operational standard. Our pre-formed structural carbon plates and strips are also often used in retrofit or upgrade systems.

Carbon Fiber Fabrics for Confining Vessels

Concrete and tile structures are susceptible to spalling after years of weathering, freeze/thaw cycles and continuous operation in harsh conditions. Gateway Composites carbon fiber fabric systems and structural glass systems are highly effective for confinement of spalls, as they provide a corrosion-resistant exterior surface for industrial process equipment such as tanks, silos, chimneys, columns, beams, slaps and piping. These systems are typically installed in the horizontal (hoop) direction and eliminate spalling of concrete and masonry tile structures.
