Material of ductwork

Galvanized iron sheet constructed to SMACNA Duct thickness I gauge Construction Standard.

Installation & Workmanship

The ductwork should be fabricated / constructed based on SMACNA Duct Construction Standard (static of 250 pa – 1000 pa). Any transformation or reducer shall be use the thickness of the larger dimension of the duct section, in the event that the duct works are accessible after the installation, the ductwork shall be immediate apply intumescent fire rated coating. All surface of the fabricated ductwork shall be clean from all stain, oil and glue etc before applying the coating by hand brusher or roller to the required minimum thickness of fire rated coating as recommended by the manufacturer.

Quality Check (QAQC)

All completed ducting shall be checked visually to ensure that they are fully completed together with all TDC joint and clip in place and coated. All coating shall be verified and checked by the system manufacture representative with "Elcometer - Digital Gauge" to ensure the thickness as recommended are met or within the recommended thickness as specified in their test reports. Any damage or insufficient thickness are then re-apply to the surface to achieve the require thickness. All repairing shall be done on dry surface (at least 12 hours duration).
