No Welding needed!  Just use self drilling hex head screws to fasten your connections.


Here are some details about the advantages of Connectube couplers:

  • Increased strength:Connectube couplers are made from high-quality steel that is designed to withstand high loads. This is achieved through a unique manufacturing process that produces a coupler with a uniform cross-section and high tensile strength. The couplers are also tested to ensure that they meet or exceed industry standards.
  • Increased safety:Connectube couplers are safer to use than other types of couplers, such as welded couplers. This is because they do not require the use of hot flames, which can be a fire hazard. Welding and lapping can create a fire hazard, especially in confined spaces. Connectube couplers are also easier to install than welding and lapping, which can reduce the risk of accidents.
  • Faster installation:Connectube couplers can be installed quickly and easily, which can help to speed up construction projects. This is in contrast to welding and lapping, which can be time-consuming and difficult to do properly.
  • Lower cost:Connectube couplers can be less expensive than other types of couplers in the long run. This is because they do not require the use of specialized equipment or trained personnel. The initial cost of couplers may be higher than welding and lapping, but the overall cost of the project can be lower.

Overall, Connectube couplers offer a number of advantages over other types of couplers. They are stronger, safer, and easier to install than other types of couplers. As a result, Connectube couplers are a good choice for use in high-performance manufacturing of steel frames.
