 ( Coated Steel Sheets + Insulations )
           - 
Steel Sheet ; -
                  PE (Silicon or Fluorine) Resin-coated Steel Sheet,
                  Zinc-Plated Steel Sheet, etc. (Th'k ; 0.5-0.8 mm)
           - Insulation ; P.I.R. Foam, Glassk Wool, etc.

        A) Ultra Panel ;-
(U.L. Marked)
             - Spec.;- T 50/70mm x W1,000mm
                          x 0.34/0.23 kcal/§³h¡É
             - Insulation  ;
                      - P.I.R.(Polyisocyanurate) Foam
                      - Better than Polyurethane Foam
                      - Incombustibility Characteristic ; U.L.Class I
                      - Application Temperature ; -196 ~ 230 ¡É
        
B) Glass Wool Panel ;- ( ISO 9002 Obtained)  
             - Spec.;- T 50/70/100mm x W1,000 mm
                           x 0.279~0.536 kcal/§³h¡É
             - Insulation ; Glass Wool
                          ( The first grade incombustible material)
             - P.I.R. Foam is penetrated into the glass wool
               to get better adhesion to both sides of steel sheet,
               enabling superior function,strength.
       
 C) Newtra Panel ;- (New best function &  fashion)
            - Spec.; T 35~100 mm x W 300~1,000 mm
                         x 0.5~0.8 S/C, A/L.
            - Solved the problem of contraction & expansion
                caused by temp.
