Exterior Metal Items rust quickly in Minnesota. To maintain them it requires regular inspection and maintenance. On certain items that are required to carry a load (like a swing stage anchor, railing supports in high areas or stairwell headers) a professional engineer should assess them. On other items (anything aesthetic or any item that if it failed would not be a hazard) a professional painting company should be able to give you an assessment of the most pressing items in need of maintenance and painting. Items on commercial properties that often times require maintenance painting are: Light poles, light pole bases, railings, metal door frames, metal entry doors, garage doors, swing stage support brackets and anything made of steel that you want to maintain its professional appearance) A few great tools that we used on this project were: Angle sanders with vacuum attachments, professional scrapers, dispensers and the correct brushes and rollers. The products were Industrial rust inhibitive primers and enamels. Complete Custom Painting LLC Painted the Teal Railing at this High Profile Building in Plymouth.
