Weight per case (30pcs)

This a clamp that uses SuperDyma (a pre-plated steel sheet) developed by Nippon Steel & Sumitomo Metal Corporation. Its corrosion resistance, approximately 15 times that of hot-dip galvanization, surely increases the service life of clamps. It is highly rated as a clamp for solar panel bases.

The bolts and rivets are hot-dip galvanized.

We provide flange nuts with a width of 7 and 16 inches for clamps.

Note: The sizes are in inches, which are not compatible with sizes in millimeters (M screws).

For scaffold construction, this liner joint can be used because it is compatible with pipes equipped with a pin.

With a single bolt, this product smoothly combines a single tube with another. As a joint for single tubes, it is designed for use at points not subjected to a bending or tensile load.

Note: This joint is not approved by Scaffolding and Construction Equipment Association of Japan; it cannot be used as a single-tube joint for single-tube scaffolds.

The lock joint is a fine product that offers the features of linear and bon joints. It eliminates gaps with pipes (unsteadiness), a drawback of linear joints. You can have it deliver the effect of a bon joint by tightening the bolt at the center. It is also compatible with thin (1.8 thick) single tubes!

[Applications of the earth-retaining steel sheet]
● Afforestation
● Prevention of road shoulder collapses
● Retention of slope-toe earth in developing land
● Emergency actions for disasters
(It is also often used for retaining earth in cultivated land.)

★ Easy to assemble, the product reliably retains earth
Consisting of only steel sheets and columns, the product can be easily and quickly assembled. With a tip specially treated, the column is easy to drive vertically. In addition, the product is based on the tensile strength of the steel sheet, which retains earth more strongly and reliably than the conventional methods.

★A wide range of applications and low costs for installation
With the flexibility of the steel sheets, the product can be formed to a desired shape according to the geographical features, providing a wide range of earth retention applications. In addition, it can be assembled with light work such as column driving and steel-sheet insertion, requiring lower costs.

★Perfect corrosion resistance
The product uses the High Color from Nippon Steel & Sumitomo Metal as the steel sheet and pipes electroplated and then baked as the column, providing an outstanding corrosion resistance.

★A variety of available colors matching natural landscapes
The product is available in three colors: greenish brown, dark brown, and green.

Earth-retaining steel sheets are used in many applications in Tokyo, Chiba, and Kanagawa prefectures. In the other areas, however, they are almost not used. We do hope that customers across Japan will experience the effect of the earth-retaining steel sheet.
If you are interested in using the earth-retaining steel sheet, please contact a business office of Heiwa Giken.
