① At the time of strong anchor work when centerline is set up mark part for fixing strong anchor (9mm) at slab surface and punch hole with drill and fix it.
② At the time of work for cash iron insert (9 mm) install it at form according to drawing.
③ Caution: Pay attention to intervals between anchor and insert and right angle.
④ It is ideal to make interval for installation as @900∼ 1,200 mm for strong anchor or insert in consideration of direction of installation of carrying channel.

① Use of water level or level
a. Confirming position by means of drawing (confirming height of ceiling)
b. Confirming the position by water level and ink pot string marking between positions.
② Caution: At the time of using water check make sure to check level after checking any presence of air bubble in hose and breaking of hose.

① Attach molding along the India ink line and fix wall molding by using 1" concrete nail.
(interval 500∼ 1,000 mm)
② Be careful not to slacken the height and interval between moldings.
③ In connection with facilities such as curtain box it shall be attached according to specification.

① Upper part of anchor bolt is fixed to strong anchor or insert and power part of bolt is fixed with hanger and nut in consideration of ceiling height at finishing.
② At the place where installation duct or other obtacles are present work shall be carried out after reinforcing it according to specification.

Install lightline according to specification but it is required to have consultation with persons in charge of electricity and facility.

After linking hanger set and carrying channel fix it and install it with an interval of @900∼1,200 mm. The joint part of carrying channel shall be connected by using carrying joint.

When area for works is broad reinforce and fix with supplementary channel (minor channel) installed above the carrying channel and install it with an interval of @2,000∼3,000 mm.

① Mark centerline for work with ink pot string and install module bar sturdily by using C/T cup in a right angle direction to carrying channel according to dimension of product and lightline.
② Intervals of module bar shall comply with drawings or specification.
③ Module bar is raised to wall molding or curtain box wing part and installed.

① Install Main ST' LT-bar sturdily by using C/T cup toward right angle direction to carrying channel according to dimension of the product and lightline.
② Intervals fore Main ST' LT-bar shall comply with drawing and specification.
③ Main ST' LT-bar is installed by placing it to wing part of curtain box.

① Accurately set level of installed ceiling frame by bolt and nut through using water level or level.
② Place finishing plate on module bar and T-bar then insert H-bar and then once more place finishing plate to T-bar and then insert it to H-bar and by repeating it work is finished.
③ Prohibit use of finishing plate with scratch, broken corner or dirtied.

① Manufacturing and installing products suitable to use according to specification (separate painting)
