The Alpha family consists of our 5 sided table systems, combined with our patent-exclusive, reversible, and replaceable top and side plates.
Alpha 28 is an Ultra heavy duty 5-sided table with 28 mm diameter boreholes.
All top plates are constructed from heat-treated steel, hardened to 550 Vickers, and finished with a nitrite coating with a case depth of .0004-.0008″.
The only modular ultra heavy duty welding table with positionable, self-locating, reversible Table Plates for unlimited possibilities in heavy duty fixturing for welding and fabrication. Accurately locate, position and clamp stock for higher quality welding.
BuildPro Engineers developed the Alpha 28 line by customer demand for an affordable, heavy duty, metric Welding Table. The five-face Alpha 28 Table is the optimal solution for precision vertical and horizontal fixturing to expand your capabilities in welding and fabrication.

The machined tubular frame construction of the Alpha 28 table provides improved flatness and torsional stiffness compared to plate only frames. The rigid frame with modular plates on the Alpha 28 means less high spots and less twisting compared to welded plate designs. The welded construction of a plate only design often leads to distortion and high spots around the corners and center.
Each plate is made from a low alloy tool steel that’s tough enough for use in the mold making industry. After surface grinding and machining, each plate is further enhanced with a QPQ nitriding process that improves hardness, corrosion resistance, and resistance to weld spatter.
Plates on the table can be repositioned, or removed as applications dictate; a patented plate locating system means the spacing of the holes are always within tolerance without the need for special re-calibration.
The unique and versatile Alpha 28 Tables are complemented by a complete range of Modular Fixturing Components and Fixturing Kits.
