GROUND DRAG MAT CO., LTD.

With a boom in the construction of the drainage systems, the demand for better pipes arose, to replace traditional concrete conduits, coupled with the shortage of workforce and rising installation costs, as well as environmental problems. steel corrugated pipe (SCP) with its high outer pressure, enhanced structural strength, durability, and affordable prices, has emerged as an alternative. The steel corrugated pipe has an ideal drainage structure that can reduce construction expense and easy to install due to its excellent structural stability and durability and long life span. steel corrugated pipe : SCP 1RS : D300mm~D1800mm steel corrugated pipe : SCP 3RS : D900mm~D2400mm Korea industrial standards : KS D 3590 Corrugated steel pipes (CSPs) are mainly used as pipes for stormwater, drainage, sewage, and wastewater and can be applied in most civil engineering sites, including arable land readjusted, forest roads established, expressways, bridges, and agricultural waterways.

PCHAINS are manufactured according to the international regulation din 8187 and din 8188. They are made by top quality steel whose mechanical features are very high. During the automatized assembly the PCHAINS are put under tension to set the dimension and to avoid strain in the initial pressure. PCHAINS are lubricated in oil , packed in plastic bags and then put in cardboerd boxes. You can find in the list the most used products. We can also supply special chains upon request such as “fragmentated” and “ringclosed”. Our technical service can give yuo further information on the materials and the special treatments we are able to offer to the customer. In 6 different dimensions they are suitable for electrical motors from size 63 (kw. 0.12 – 4 poles) to size 180 (kw.22 – 4 poles). The adjustable Motor Mountings are designed to solve the problem of the belt tension in power transmission.

The attachment chain may only be used as an attachment accessory without edge protection if a 20% reduction in load lifting capacity is taken into consideration or if the nextlargest chain thickness is used. Otherwise, a secutex SKK hinged edgeprotector must be used. A “sharp edge” exists when the edge radius is smaller than the nominal thickness of the lifting chain. Further information is available in the “sharp edge“ chapter.

Even when securing the load, the lashing material must be protected from the “sharp edge“. Highvalue loads may not be damaged by lashing chains. The secutex SKKE simple edgeprotector is simply placed onto the chain via the slit on the reverse side, making it impossible to lose. The edgeprotector is light and flexible. Due to the low deadweight and flexible textile reinforcement, the edgeprotector can be attached easily and quickly to the load. Important note The secutex SKKE simple edgeprotector is not intended for prolonged use.
