Our Manufactured dock system begins with the our choice in steel. Our use of high tensile strength, American made steel, is the best way to ensure the strongest structure. Our precision laser cut coupler for 90 degree joints (Manufactured by a local fabrication shop) is the strongest on the market. Attention to detail and our quality control team inspect all products before and after assembly. 3.5′, 4′, 5′, 7′,8′ and 10′ widths are our standard sizes. Custom dimensions and configurations are available upon request!!!
