Denso protects marine structures with the SeaShield Series

Four types of SeaShield protection systems are available from Denso.

Wharf piles, riser pipes, and exposed piping are vulnerable to water damage in bridges, waterfront terraces, and other marine structures. Denso North America has the right solution: the SeaShield series of corrosion-prevention and sealing products. This is a series of protection systems designed for splash zones in marine applications. SeaShield systems protect steel, concrete, timber, and other materials from corrosion damage with petrolatum tapes, fibreglass jackets, epoxy grouts, and more.

Systems for splash zones

Canadian customers have access to several types of Denso SeaShield systems:

• Series 2000HD – This series offers steel and concrete-pile protection for wharf piles, riser pipes, and exposed piping in intertidal and splash zones. The system accommodates piles with cylindrical configurations, as well as irregular surfaces like support members, bracing, and brackets. This system utilizes Denso petrolatum tape and a bolted HDPE jacket to protect the pile and seal out oxygen and water, in order to prevent corrosion of metal surfaces.
• Series 100 – Like Series 2000HD, this category provides steel, concrete, and timber-pile protection with minimal surface preparation. Ideal for conditions that are too harsh for paint systems, epoxies, and other conventional forms of protection. A high-density-polyethylene (HDPE) outer cover protects the petrolatum tape and the outercover is held in place by banded strapping.
• Series 90 – Recommended for protecting timber piles, including hour-glass piles, posting, and bracing. This series protects timber supports against marine borer destruction and deterioration from weathering, by sealing out oxygen with Denso petrolatum tape and then adding a durable HDPE jacket that is nailed to the pile.
• Series 500 – Heavy-duty pile protection with fibreglass jackets, to repair coastal marine structures and protect from corrosion. Perfect for jetty piles, bridge supports, offshore risers, conductors, jacket legs, and structural member support. The system can be adapted for different pile shapes and sizes, both above water and underwater. Users secure the fibreglass jackets to the pile and then fill them with Denso 550 epoxy/grout.
