Three Environments That Eat Steel Decks

Steel decks fail fastest where water carries something aggressive with it. CorroShield was formulated for the three worst offenders:

1. Parking Structures

Every winter, vehicles carry chloride-laden slush onto steel-framed parking decks and ramps, and every spring the corrosion bill comes due. De-icing salts penetrate thin traffic paint immediately and attack the deck plate and its welds. CorroShield builds a chloride-impermeable elastomeric layer over the entire plate — including the drain slopes and expansion details where brine sits longest — with an aggregate-textured surface that takes tire traffic and snow-plow abuse.

2. Marine and Waterfront Structures

Docks, pier decking, barge covers and shoreline platforms live in the splash zone: alternating wet-dry salt exposure that corrodes steel several times faster than either full immersion or dry air. The membrane's 400% elongation matters here because marine structures work constantly — decks flex under wave and berthing loads, and rigid coatings crack at exactly the welds that need protection most. CorroShield stretches through that movement and stays sealed at the plate.

3. Industrial Platforms and Process Decks

Elevated steel around processing equipment sees chemical splash, hot washdowns and point-loaded traffic from carts and racks. A seamless film with no joints means there is nowhere for wash water and product to hide against bare steel between cleanings.

Getting Steel Ready

Corrosion service demands better prep than cosmetic work, and our specification reflects it:

Abrasive blast to SSPC-SP6 commercial blast with a 2–3 mil angular profile on decks with established corrosion, or SSPC-SP3 power-tool cleaning on lighter service.
Salt contamination testing on parking and marine work — chlorides left under any coating cause osmotic blistering, so decks are tested and washed until soluble salt readings pass.
Weld and edge detailing: sharp edges ground, weld spatter removed, and a stripe coat applied on every edge and weld seam before the full membrane passes.

Application runs at 50–120°F substrate temperature, above dew point. Tack-free in seconds means a parking level or pier section returns to service in hours, not days — often the deciding factor for structures that cannot close.
