Onlinemetals’ baseplates provide a versatile foundation for structural fabrication, fixture building, and custom metal projects, featuring both standard 4-hole A36 steel baseplates and the innovative EZ Tube® baseplates designed for the EZ Tube square tube press-fit system. The A36 steel baseplates are weldable, durable, and ideal for anchoring posts, frames, guards, and machinery to floors or other structures, making them a reliable choice for construction, industrial, and shop applications. EZ Tube baseplates are precision-designed to press-fit seamlessly into square tubing, creating strong, square, and repeatable connections without the need for complex machining, while still allowing for welding or bolting as needed. Together, these baseplate options give fabricators, manufacturers, and DIY builders a fast, accurate, and cost-effective way to create stable, professional-grade assemblies.
