Shinsung C&S Ltd, has launched the non-welding truss construction method

[Written by Journalist Ms. Lee Kyung-ok, of Kookto Ilbo] Shinsung C&S Ltd (CEO, Lee Sung-do) released the news that it had jointly developed the non-welding truss construction method, proven to be effective for fire prevention at construction sites, in cooperation with the POSCO, and NT Steel, etc.

 

Recently, industries are seeking ways to minimize welding at construction sites as construction sites have seen a gradual increase in large fires caused by welding operations. In response, a method for non-welding truss construction has been developed and has garnered attention. This method has been evaluated to identify the needs of industry accurately and found to comply with government measures and related acts for fire prevention at construction sites.

 

Most fires and explosions at construction sites occur during the process of welding and fusing during the past three years. Fire causes not only massive physical and human damages, but also results in immeasurable damage due to construction delays. To prevent fire accidents, a fire supervisor is deployed to the following construction sites where the risks of ignition are high –welding and fusing on flammables; flammable gas plumbing and cylinders; and urethane formed insulators, etc.

For this reason, cost-reduction effects are expected in fire management.

Amidst this environment, Shinsung C&S Co. Ltd actively explored ways to install trusses at construction sites without welding. The solution is the non-welding system. This system allows for fastening of screws and bolts by using connection device to horizontal and vertical structural steel pipes. Fixed brackets can be inserted and fastened to the depressed surface of the central part of a steel section.

 

As welding is skipped, construction period and costs can be saved. Its feature of eliminating the risk of fire is possible due to the screw and bolt assembly. As it can be done by a general assembler, costs can be reduced, and the lift-up method can also be implemented.

 

Due to its streamlined process, the non-welding system reduces the construction period by 30% compared to the welding system. It takes 15-20 days for one team (three members) when they work on 1,000㎡ with a non-welding system while it takes 30 days for one team (five members including a fire supervisor) when working with a welding system on the same area.

 

The same construction and quality can be secured. Quality can vary in a welding system depending on the welder’s level of ability and skill. However, consistent high quality can be secured with a non-welding system regardless of the welder’s proficiency.

 

Shinsung C&S Co. Ltd has secured expertise in various areas including steel distribution, coil processing facilities, steel pipe manufacturing facilities, reinforcement materials for windows and doors, etc. since its establishment in October 2009.
