Vinyl tread plates are lightweight and more affordable and, therefore, make a suitable alternative to metal tread plates in use in such areas as warehouses or light-foot traffic areas.
Stainless steel tread plates come with distinctive features that qualify them for demanding applications. Such features include:
Corrosion Resistance
Stainless steel tread plates come with exceptional corrosion resistance, which prevents them from rusting and degrading, especially in challenging environments, such as outdoor areas and industrial settings. The alloy's incorporation of chrome forms a protective layer that averts moisture and oxygen from penetrating the metal. This retardant to corrosion makes stainless steel tread plates ideal for applications requiring durability and longevity.
Slip Resistance
Apart from their strength and durability, the prominent characteristic of stainless steel tread plates is their ability to provide slip-resistant and safe surfaces. The checkered or diamond pattern increases traction, which is especially useful in areas where spills or wet conditions are normal. It helps to avert accidents and improve safety in use on walkways, ramps, and working platforms.
Strength and Durability
The strength of stainless steel tread plates results from the chemical composition of the steel, which incorporates nickel and molybdenum. These materials enhance the tensile strength and make the plates shock-resistant to impacts and heavy loads. Stainless steel comes with superior hardness when compared to other metals and helps in resisting dents, scratches, and wear and tear.
Easy Maintenance
Stainless steel tread plates are easy to maintain due to their impermeable and non-porous surface. This characteristic of making the dirt, grease, and other contaminants easy to remove enables them to be easy to clean. In addition, the resistance to chemical attacks, such as from detergents and harsh industrial agents, further facilitates their applicability in hygienic-sensitive areas such as food processing facilities and medical facilities.
Aesthetic Appeal
Apart from their functional properties, stainless steel tread plates have sleek modern appearances. They have a shiny, reflective surface that can be appealing in building interiors and exteriors. In addition, the signature diamond or checkered patterns provide an industrial charm that makes them suitable for both practical and design-oriented objectives in construction and renovation projects.
When choosing a stainless steel tread plate, it is imperative to consider several factors to meet the intended use. Here are some guidelines to help in making an informed decision:
Type of Stainless Steel
Different grades of stainless steel offer distinctive properties. Commonly, Stainless Steel 304 is used as the standard grade due to its excellent resistance to corrosion and ease of fabrication. Usually, Stainless Steel 316 comes with enhanced corrosion resistance, especially in marine or chemical processing environments. Therefore, select a grade that meets the specific environmental conditions the tread plate will be exposed to.
Thickness and Size
The required thickness of the tread plate normally depends on the application. Usually, heavier gauges offer more durability and are ideal for heavy traffic or industrial usage. Also, ensure the size of the plate is fit for the area of installation. Most importantly, while standard sizes are available, often, they can be customized depending on requirements.
Finish
Stainless steel tread plates are usually available in various finishes, from brushed to polished. Each finish affects the level of shine and the degree of slip resistance. Standardly, a brushed finish is less reflective and provides better grip, while a polished finish provides superior aesthetic appeal with relatively low level of slip resistance. Select a finish that meets both functional and aesthetic requirements.
Load Capacity
It is important to consider the weight and load the tread plate will support. Normally, the plate must have sufficient strength to handle the expected loads without warping or compromising the surface's integrity. Typically, this is especially critical in industrial settings where heavy machinery or foot traffic is common.
Stainless steel tread plates are versatile as they are widely used in such industries as construction, transportation, and equipment manufacturing. Common applications include:
Walkways and Flooring
Widely, stainless steel tread plates are applicable in walkways and flooring in both industrial and commercial settings. Their slip-resistant surface makes them ideal for areas with high foot traffic, such as factories, warehouses, and outdoor installations. In addition, they provide durability and corrosion resistance, which is useful for maintaining safety over extended periods.
Ramps and Staircases
Often, stainless steel tread plates are used on ramps and staircases, giving a safe and sturdy surface. The traction pattern prevents slipping, especially in wet or oily conditions, making them suitable for use in such places as maritime facilities, parking garages, and power plants. Additionally, they withstand the wear and tear that comes from constant use.
Exterior Cladding and Panels
Commonly, stainless steel tread plates are used to provide an aesthetically appealing and functional exterior cladding in architectural applications. Typically, they are used in high-rise buildings, public infrastructures, and bus and train stations. Their resistance to corrosion and vandalism makes them suitable for outdoor environments. Therefore, they aid in protecting structures from harsh weather elements.
Automotive and Marine Applications
Stainless steel tread plates are used widely as functional and decorative components in the automotive and marine industries. Ideally, they are applied in truck beds, toolboxes, and pedestrian areas in ships and boats to provide a slip-resistant surface. In addition, their ability to resist saltwater and marine chemicals makes them suitable for maritime environments.
Equipment and Tool Manufacturing
Ideally, in equipment and tool manufacturing, stainless steel tread plates are used to make platforms, foot pedals, and protective covers. Usually, they add durability and grip to machinery and tools. Also, it aids in preventing user slippage or injury when operating equipment in industrial settings such as construction sites and mining operations.
The short answer is yes. While mechanical fasteners are the most reliable method for securing a stainless steel tread plate, as a rule of thumb, tread plates can be adhered using heavy-duty construction adhesives in specific applications where mechanical fastening is impractical. Ideally, these adhesives provide a sufficient bond that holds the plate in place as much as possible under typical conditions. Under extreme conditions, such as heavy loads or significant foot traffic, consult the manufacturer to determine whether using glue is a long-lasting solution.
Usually, stainless steel tread plates are completed with a variety of finishes, and each has unique aesthetic and functional benefits. Commonly, brushed finish is characterized by a satin-like appearance with fine linear polish scratches that promote corrosion resistance and reduce gleam. On the other hand, a mirror finish is highly reflective and gives an appealing and clean surface that is easy to wipe down and clean. Lastly, a sandblasted finish contains a matte appearance with higher grip due to its rough texture, thus improving slip resistance and minimizing glare.
Usually, stainless steel tread plates are manufactured from stainless steel sheets, which are typically rolled to a specific thickness. The plate is then treated with heat to soften the material, thus enabling it to be mechanically embossed with the distinct checkered or diamond pattern. The plate undergoes a series of forming dies in a hydraulic press. Finally, it is polished and, at times, coated to improve both appearance and resistance to corrosion.
