Stainless Steel Square Base
The Stainless Steel Square Base offers a refined, modern foundation for dining-height tables in hospitality settings. When designers want a premium finish paired with a strong support structure, they often compare this model with the JIS3-18TP12 / JIS3-22TP12 family to ensure match in material and footprint. This square-footprint version brings the same brushed stainless steel aesthetic with a larger plate for added stability.
What It Is
The JIS3RD-18SQTP12 and JIS3RD-22SQTP12 models belong to the stainless steel square base line from JI Bases. These dining-height units share a 29-inch overall height and use round stainless steel columns with square base plates. For layouts that also include end-mounted supports, you might use the JIS3-522TP12 End Base in the same finish to keep design consistency across seating types.
At a glance
Dining height 29″. Footprint 18″×18″ or 22″×22″. 3″ stainless-steel round column. Brushed #304 stainless finish. Four adjustable glides.
Size & Compatibility
The 18×18-inch version suits smaller tables, whereas the 22×22-inch version gives more mass under larger tops. Both support square or round tabletops with confidence, especially when paired with other high-end stainless bases. Some designers match them to pieces like the JI4-28RDTP17-2 to maintain a cohesive metal aesthetic across zones.
Use Cases
This base is ideal for upscale restaurants, hotel dining rooms, and modern residential hospitality areas where design and durability both matter. The square plate aligns well for booth seating or along wall layouts, and the stainless finish complements architectural metal accents. When you’re specifying support for a wide range of table sizes but want consistent finish and geometry, the square base offers standardisation without compromise.
Design insight
Square base plates offer visual symmetry and floor alignment that often works better with grid layouts and aligned furniture runs than round plates.
Installation and Setup Tips
Ensure each base sits level before securing the top plate to the tabletop. Align bolt patterns and adjust glides so all four contact points are firm. Confirm your flooring and bracket connection are stable given the additional weight of stainless. When switching finishes across zones, use matched bases rather than mixing materials to maintain a unified appearance.
Installation reminder
Do not forget to ask us to Pre-drill your Restaurant Tables. You will spend a few hundred dollars with us, or a few thousand dollars for installers to do it during install.
