Floor Cover Plates

What Are Floor Cover Plates?

Floor cover plates, also known as expansion joint covers, are designed to bridge gaps between flooring surfaces while protecting expansion joints from damage and wear. They create a smooth transition across floor openings, helping to improve safety, maintain structural movement requirements, and provide a finished appearance in commercial, industrial, and institutional environments.

Available in aluminum and stainless steel, floor cover plates are commonly installed where concrete slabs, flooring systems, or building sections require controlled movement due to thermal expansion, contraction, or structural shifting.

Common Applications for Expansion Joint Cover Plates

• Commercial office buildings
• Shopping centers and retail stores
• Hospitals and healthcare facilities
• Schools and universities
• Warehouses and industrial facilities
• Airports and transportation terminals
• Government and municipal buildings
• Parking garages and service corridors
• Manufacturing plants
• Multi-family residential developments

Benefits of Floor Cover Plates

• Protect expansion joints from impact and debris
• Create safer walking and rolling surfaces
• Reduce trip hazards between floor sections
• Accommodate building movement and expansion
• Available in ADA-friendly and wheelchair-accessible designs
• Durable aluminum and stainless steel construction
• Suitable for high-traffic commercial environments
• Available in smooth and slip-resistant diamond tread finishes

Types of Floor Cover Plates Available

TM Hardware offers a wide range of floor cover plates and expansion joint covers to meet different project requirements:

• Aluminum Cover Plates – Lightweight, corrosion-resistant, and ideal for most commercial applications.
• Stainless Steel Cover Plates – Designed for demanding environments where durability and corrosion resistance are critical.
• Diamond Tread Plates – Slip-resistant surfaces for industrial and high-traffic areas.
• Expansion Joint Covers – Designed to accommodate structural movement while maintaining floor continuity.
• Neoprene Extensions – Flexible accessories for additional joint coverage and movement.

How to Choose the Right Expansion Joint Cover

Selecting the proper floor cover plate depends on joint width, traffic requirements, load conditions, and environmental exposure. Aluminum models are often sufficient for offices, retail spaces, and schools, while stainless steel options are preferred in healthcare facilities, food processing environments, and areas exposed to moisture or corrosive conditions.

For facilities with carts, wheelchairs, or heavy pedestrian traffic, ADA-compliant and smooth transition designs help improve accessibility and safety.

Industries That Use Floor Cover Plates

• Healthcare and medical facilities
• Hospitality and hotels
• Retail and shopping centers
• Education and universities
• Industrial manufacturing plants
• Transportation hubs and airports
• Government facilities
• Commercial office buildings

Frequently Asked Questions

What is a floor cover plate?

A floor cover plate is a metal plate designed to cover floor gaps, expansion joints, or uneven transitions while maintaining a safe and durable walking surface.

What is an expansion joint cover?

An expansion joint cover protects structural expansion joints while allowing buildings and flooring systems to expand and contract naturally.

Are floor cover plates ADA compliant?

Many floor cover plate designs are suitable for ADA-compliant applications when properly selected and installed to minimize vertical changes and trip hazards.

Should I choose aluminum or stainless steel?

Aluminum is cost-effective and corrosion-resistant for most projects, while stainless steel provides superior durability and performance in demanding environments.

Can floor cover plates be used in high-traffic areas?

Yes. Heavy-duty expansion joint covers and diamond tread cover plates are specifically designed for areas with significant pedestrian, cart, and equipment traffic.
