Tabletops, Alpha 28
Welding tables come in a variety of sizes to suit your unique fabrication needs. The five face design of the table using 25 mm thick plates and reinforcements underneath creates an extremely rigid table surface. A plasma nitride finish comes standard on all tables for a work surface extremely resistant to wear, deformation, corrosion, and weld spatter.
More Details
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.

Table Top Plates are made from tough P20 low alloy tool steel for a 60.5HRC hardness, then CNC machined for flatness.
QPQ Nitriding Treatment provides corrosion and weld spatter resistance for superior performance and wear.
Patented, self-locating Table Plates can be repositioned, then easily realigned to the original position. Reposition the table plates as needed to increase the width of the table for oversized or complex fixtures.
2X Life! After showing signs of wear, Alpha 28 Table Plates can be reversed to provide a new work surface.
Each Heavy Duty Table leg supports 4,400 lb [2,000 kg].
Alpha 28 tables feature 6 legs compared to competitors’ 4 legs on 2.4 x 1.2 and 2.1 x 1.0 table sizes for greater rigidity and flatness
