Collection: Continuous High Chairs

Continuous High Chairs – Stable, Uniform Support for Multi-Layer Rebar Placement

Continuous High Chairs are essential for maintaining consistent spacing and concrete cover between multiple layers of reinforcement in slab, beam, and precast applications. Designed to support upper mats of steel above lower reinforcement or formwork, these chairs are built for strength, stability, and code-compliant performance. At Bolsinger Rebar, we offer a full selection of plain, plastic-tipped, epoxy-coated, and upper continuous high chairs to match your project’s technical and environmental needs.

Plain Continuous High Chairs

Our standard plain steel high chairs are made from welded wire with a continuous top runner and stable base supports. They are ideal for use in general slab and precast applications where corrosion exposure is minimal. These chairs ensure proper top-mat elevation while resisting movement during concrete placement.

Plastic-Tipped High Chairs

Plastic-tipped high chairs feature plastic-covered feet to protect vapor barriers, membranes, or form liners. These are ideal for exposed architectural concrete, slabs over waterproofing, or any condition where direct steel contact with the form or base is undesirable.

Epoxy-Coated High Chairs

When corrosion resistance is critical—such as in parking structures, bridge decks, marine applications, or DOT projects—epoxy-coated high chairs offer added protection. These chairs are coated with a durable green epoxy to resist rust and chemical exposure, ensuring long-term durability in harsh environments.

Upper Continuous High Chairs

Upper high chairs are specifically designed to support top-layer rebar in double-mat systems. With taller legs and a reinforced top runner, they span over the lower mat to hold top bars at the proper elevation, making them ideal for thick slabs, mat foundations, and elevated structural concrete work.

Key Features:

• Available in plain, plastic-tipped, and epoxy-coated finishes
• Supports rebar at required height with minimal deflection
• Manufactured in standard lengths (typically 5' pieces)
• Offered in multiple heights to meet various concrete cover needs
• Easy to install and tie, reducing setup time on site
• Conforms to ACI and project specification standards

Common Applications:

• Multi-mat reinforcement in slabs and beams
• Precast and cast-in-place concrete systems
• Parking structures, bridge decks, and water treatment facilities
• Architectural concrete with finish requirements

Bolsinger Rebar’s Continuous High Chairs provide the strength, stability, and flexibility needed for efficient rebar placement and long-term performance. Whether you're working with standard concrete, aggressive environments, or precision architectural pours, we have the high chair solution to support your project’s success.
