The Screed Angle Frame Bar operates on mechanical leveling. It consists of a rigid, high-strength brass frame, with adjustable angle brackets at each end. These bars allow for precise adjustment of the screed angle to accommodate varying thicknesses and surface gradients of the angle.Attributes:• Withstands high loads and extreme operating conditions• Provides excellent strength, toughness, and wear resistanceApplications:The Screed Angle Frame Bar is the straight-edge board attached to the frame and is the primary surface contact with the wet concrete.
