Specific recommendations for construction of metallic surfaces exposed to corrosion are made. The author points out total exposed areas may be reducd by adopting the proper shapes of structural members, by enclosing with planar plates structures including angles and braces. Seal welding is recommended.
The design engineer is warned to keep in mind structures exposed to atmosphere ultimately require surface preparation and that an effort should be made to minimize inaccessible areas. Consideration should be given to the need for ultimate painting by providing as many plane surfaces as possible. Welding is favored over riveting. Specific recommendations are made concerning design which offer the best possible way of minimizing corrosion damage.
