Soft Material (CQ) is more suitable for complex architectural design due to its good formability properties whereas hard material (SQ) has limited formability. Thus, CSC Steel Sdn. Bhd. has variety steel grade which is in range of CQ, SQ and Full Hard as compared to others

realcolor® Thermoshield coating system has hydrophilic technology (refer below mechanism) that works by shifting off dirt particles from the coated substrate rather than dirt particle sticking, drying and embedding on the surface.
Product Normal PPGI realcolor®Thermoshield
Water contact, Ѳ = 80-90°C

Hydrophilic Surface
Water contact, Ѳ = <20°C
Heat Transfer Mechanism

Generally, solar radiation gives out light and heat to the earth in the form of electromagnetic waves (ultraviolet, visible and infrared). Majority of heat is come from visible and infrared range. realcolor® Thermoshield product able to reflects and emits most of the energy near infrared range. Thus, this will help reduce the amount of heat adsorbed into a structure and keep the shelter environment cool.
GI coating is purely Zinc, shall provides more protection to steel substrate by the sacrificial loss of Zinc in the vicinity of the exposed substrate (cut edge and scribes), as compared to GL. GL coating is more fragile and easily cracks at bended areas, resulting in steel metal being exposed to atmospheric elements at these areas.

Cut Edge Protection - Galvanic protection will in place until all the Zinc has been consumed

Furthermore, GL also poor in alkaline resistant compared to the GI (Please refer Q9). Therefore GL is not suitable to be used in agriculture facilities.
PPGI that produced under CSC STEEL brand realcolor® Primero/Thermoshield/Supreme have been properly designed, manufactured and tested out to have outperforming performance when compare to equivalent PPGL under same environmental conditions. 2000hrs of salt spray test (SST) simulating the corrosion resistances of realcolor® Primero versus PPGL panel has been made and results are presented as below.
Life span of metal roofing can be extended by cleaned the paint film surface at least annually with mild detergent or clean neutral water. Paint film surface must not be cleaned with abrasive or chemical cleaners
There are a number of simple steps that can greatly reduce or eliminate the formation of white rust. These are:
  • Keep the packed work dry
  • Pack the items to permit air circulation between the surfaces
  • Stack the packed items to allow water to drain out
  • Treat the surface with proprietary water repellent or barrier coatings to prevent moisture contact with galvanized surface
Touch up paint can be used to repair or cover up minor scratches. For further information, please contact technical person from CSC Steel Sdn. Bhd.
