The steel encasements must be painted. Please use ENG. Spec. #10068. The product for powder coating is from Tiger-Drylac Spec. #149/15320, Color:RAL1015 (Bamboo Beige). Attached is a picture of the existing lead panel steel encasement for your reference. Product Info and SDS are located here: https://www.tiger-coatings.com/us-en/downloads.

Where the lead is not protected by the steel casing, raw lead must not be exposed and needs to be covered with a wear-resistant coating. The manufacturer shall propose a product for LBNL to review.
