Attach hanger rods directly to structural steel — no drilling required. Welded beam attachments are weld-on anchors for connecting hanger rods to beam flanges. The standard solution for anchoring mechanical system hanger rods to structural steel in commercial and industrial buildings. Weld-on design — permanently attaches to beam flange for high-load applications Accepts standard threaded hanger rod (3/8" or 1/2") Supports pipe hanger, strut, and equipment suspension loads Pre-Galvanized construction MSS SP-58 / SP-69 compliant ✔ In Stock — Ships Same Day or Next Business Day✔ Used by contractors and professionals✔ Designed for reliable jobsite performanceOverviewWelded Beam Attachment with Hardware Plain Finish 3/8" is a welded beam attachment for connecting threaded hanger rods to structural steel beams in commercial and industrial mechanical systems. Welded beam attachments are permanently welded to the beam flange and provide the highest load capacity — required on heavy mechanical systems and seismic applications. Once installed, standard threaded hanger rods connect to the attachment to support pipe hangers, strut channel, or equipment below.Common Uses Anchoring hanger rods to structural steel beams Supporting pipe hanger systems from steel framing Suspending strut channel from beam flanges Mechanical, electrical, and plumbing system support Commercial and industrial building construction Key Features Weld-on design — highest load capacity, permanent attachment Threaded rod connection (3/8" or 1/2" rod) Pre-Galvanized construction MSS SP-58 compliant load rating Specifications Type Welded Beam Attachment Finish Pre-Galvanized Installation Weld-On Rod Connection Threaded Rod (3/8" or 1/2") Standard MSS SP-58 / SP-69 Frequently Asked QuestionsWhat is a beam attachment used for?Beam attachments provide an anchor point on structural steel beams for connecting hanger rods that support pipes, strut channel, and mechanical equipment below.Welded vs. clamp-on beam attachments — which do I use?Welded attachments are permanently fixed and carry higher loads — required for heavy systems and seismic applications. Clamp-on attachments install faster, require no welding, and handle most standard commercial pipe support loads.What rod size do beam attachments accept?Most standard beam attachments accept 3/8" or 1/2" threaded hanger rod. Heavier-duty versions accept larger rod sizes.Do beam clamps damage the structural steel?Clamp-on beam attachments grip the flange without welding or drilling — they do not damage or modify the structural steel and are removable if needed.Why Contractors Choose This Product Weld-on design provides the highest load capacity and is required for heavy mechanical systems and seismic-braced installations Standard threaded rod connection is compatible with all standard pipe hangers and strut fittings MSS SP-58 compliant — meets the pipe support engineering standards required on commercial and institutional jobs PVFPro stocks both weld-on and clamp-on styles across standard load ratings Buying in volume?
