Heavy machinery

Engineered protection for equipment that never stops working. Heavy machinery operates in environments defined by extreme forces, abrasive materials, vibration, heat, hydraulic systems and demanding duty cycles. From quarries, foundries and steel mills to construction equipment, bulk handling systems and large-scale industrial plant, every penetration must withstand multi-hazard exposure while maintaining the reliability and safety that heavy industry depends on.

“The service provided by CSD was excellent in all aspects. The installation crew were skilled, hard-working and resourceful and also integrated well with our own men who supported then with the external duct sealing.”
