MAIN FEATURES

1. Working process is shortened.NK supports are used as both shoring and sca�olding for a platform to operate the concrete form. It does not require changes for bar arrange-ments, so this saves labor and the working process is shortened.

2. Strong bearing powerA single NK support has the bearing power twice as strong as a frame shoring (or a frame leg). Furthermore, NK supports can be assembled easily.

3. Improvement of working ability.Unlike frame shoring, NK supports can be adjusted �exibly in various widths and spans.

The brace can be installed or removed easily depending on circumstances. NK supports are light and very easy to move.

4. Simple structureThe joint for NK supports can be connected by plugging with using a hammer only, so NK supports are very easy and speedy to assemble and dismantle.

5. Easy shipmentNK supports can be transported and carried out separately within limited space and through small holes such as manholes.

6. Rust preventionNK supports have a distinct advantage over corro-sion and rust due to hot dip zincing method.
