One of the best ways to prevent corrosion of your steel deck is to coat it with a primer that inhibits rust or. If you read all of your ASK D-MAC emails, you may remember that for the 1.5 roof deck, SDI argues that no reinforcement or repair is necessary for holes or dents less than 6 inches in diameter and that do not impact more than two vertical nets.

Forklift & crane repair, installation & service. For premium painted roofs, the Steel Deck Institute (SDI) Roof Covering Design Manual states: “Premium paints by nature are transitional and temporary. The steel elements of your platform are in the insulation, so most often corrosion problems are encountered on the platform when dealing with leakage problems. If the type of platform used is not available in the construction documents, the type, gauge and finish of the platform must be determined on site.
The roof deck varies mostly between 22 and 16 calibers and the lightweight concrete deck varies between 28 and 20 gauge. Sometimes these slabs are also not reinforced, depending on the size of the platform and whether or not it has anchor bolts with heads that drill into the platform to attach the concrete to the frame below. Metal roof deck, formwork deck and composite floor decks are available in all types, gauges and finishes for immediate use, as well as for any size order produced for any requirements and project schedule. Metal Deck Supply is a full-service metal decking distributor with 15 locations in 11 states serving the U.
However, if you know there is a steel deck underneath the insulation and you notice leaks or pond problems, there is a good chance your steel deck has been affected. They soon realize that large areas of the deck will have to be replaced, and the project comes to a halt as teams try to figure out what kind of platform is needed and how long it will take to get it to the job site. He says he can't remember a roofing job on a metal deck that didn't require replacing at least some part of the deck. D'Annunzio and Horwath recommend specifying the replacement cost of the platform on each contract, even if the platform looks perfect.

Research has shown that the composite floor deck that is damaged but does not fail during concrete pouring performs as well in service as the undamaged floor deck. Minor openings, such as small holes, can be covered with metal plates or with an overlay of a metal roof panel that attaches to the existing metal deck panel.
The metal deck only needs to be replaced if the damage is serious enough to affect its structural performance, which is clearly defined for 1.5 decks, but requires engineering judgment for floor coverings.
