Plastic Shim Weight Capacity: Understanding Safe Load Limits

Plastic shims are a versatile tool with a variety of applications, from glass installation to aligning stone and levelling appliances. They are ideal for both industrial and residential use and are known to be stronger and more durable than wood, as well as lighter than metal. When it comes to weight capacity, plastic shims can vary depending on the brand and specific material. Some plastic shims can hold up to 20 tons, while others are designed to support 16,000 pounds of pressure. The Wobble Wedge plastic shim, for example, can hold up to 2,000 lbs without shifting or slipping under pressure. The weight capacity of plastic shims makes them a reliable choice for various applications, ensuring stability and support.

Plastic shims can withstand up to 20 tons of weight

Plastic shims are a versatile tool with a wide range of applications in both industrial and residential settings. They are commonly used in construction, glass installation, and for aligning stone surfaces. One of the key advantages of plastic shims is their impressive weight-bearing capacity.

The weight-bearing capacity of plastic shims makes them ideal for levelling and adjusting uneven surfaces. They can be placed under appliances, such as washing machines, dryers, and refrigerators, to ensure they are stable and level. Plastic shims are also useful for temporarily fixing wobbling furniture, such as chairs or tables, that move under weight.

In construction, plastic shims are used to level concrete pavers, blocks, and steps. They can also be placed under stone slabs to prevent wobbling or rocking. Additionally, plastic shims are valuable in glass installation, where they can handle the weight of large commercial plate glass without crushing or damaging the edges.

The strength and durability of plastic shims make them a superior alternative to traditional wood or metal shims. Unlike wood, plastic shims are resistant to crushing, rot, and deformation over time. They also offer the advantage of being lighter than metal while providing comparable strength. Plastic shims are easy to work with, as they can be cut to size and nailed or screwed into place, making them suitable for both temporary and permanent applications.

They are ideal for heavy-duty applications

Plastic shims are ideal for heavy-duty applications. They are used to level and adjust heavy loads and are designed to be easy to use. They are frequently used in construction and building applications, such as levelling concrete panels during the assembly of warehouses and aligning window and door frames in residential dwellings. They can also be used in large projects such as glass storefronts, where panels must be aligned with each other and the frame.

Plastic shims have a high compressive strength and can withstand a lot of weight. They are weight-tested to 20 tons and can bear the weight of windows, providing smooth window operation. The compressive strength of plastic shims made with polypropylene plastic via injection moulding can be between 4,500 and 6,000 psi, resulting in a compressive strength of 40,500 and 54,000 psi for a shim with a surface area of 9 sq. inches.

Plastic shims are also stackable, which means they can fit virtually any size joint by combining standard sizes. They can be easily cut to size and are available in a variety of widths and shapes. Additionally, they are coloured by thickness, which simplifies and speeds up selection and installation.

Plastic shims offer several advantages over traditional wood and metal shims. They do not rot, degrade, or rust, and are resistant to most oils and chemicals. They are also inert, meaning they will not react with or chemically affect the materials they touch. This makes them ideal for separating dissimilar materials that would otherwise react with each other, such as aluminium and concrete or steel.

Plastic shims are used to level and adjust

Plastic shims are commonly used in construction work for accurate levelling and alignment. For example, in tilt-up concrete construction, plastic shims are used to level and align panels before they are permanently attached. In stone masonry and stone panel cladding, plastic shims provide temporary joint spacing and help relieve stress while the mortar sets. Plastic shims are also used in wall and roof panels, doors and frames, and entrance, storefront, and curtain wall systems for alignment and spacing.

In addition to construction applications, plastic shims are used in a variety of other industries. For instance, in the glass and windows industry, tapered plastic shims are used for levelling and aligning dead loads. In amusement park structures and equipment, plastic shims provide levelling and alignment, and in HVAC equipment, they are used for alignment before permanent fixation. Plastic shims are also used in kennel enclosures and gates, elevators and escalators, and heavy objects such as parking equipment and loading dock equipment for temporary alignment before permanent fixation.

The versatility of plastic shims lies in their ability to be customized for specific applications. They can be made from different plastics, such as polypropylene, high-impact polystyrene, or ABS, and can be colour-coded to indicate thickness. Plastic shims are also stackable, allowing them to fit various joint sizes, and can be heat-welded to form permanent stacks. Overall, plastic shims offer a durable, adjustable, and compatible solution for levelling and adjustment tasks in a wide range of industries.

They are made of polypropylene, which has high compressive strength

Plastic shims are used in construction to bridge irregular gaps and are ideal for heavy-duty precast tilt-up concrete panel installers. They are also used where heavy loads are set on top of them, often permanently. Plastic shims are made of polypropylene, a material with high compressive strength.

Compressive strength refers to the ability of a material to withstand compressive forces before it deforms or breaks. It is measured in stress units, such as pounds per square inch. The compressive strength of a material depends on its type and quality. Plastic shims are made of polypropylene, which has a high compressive strength, making it suitable for use in construction.

Polypropylene is a type of plastic with excellent chemical resistance and inert properties. It is often used to separate dissimilar materials that would otherwise react with each other, such as aluminium and concrete or aluminium and steel. In addition to its high compressive strength, polypropylene is also known for its impact resistance, which is the ability to withstand a sudden force without breaking or crushing. This makes polypropylene an ideal material for plastic shims, as they need to be able to support heavy loads without failing or fracturing.

The high compressive strength of polypropylene plastic shims offers advantages over hollow shims or wood shims. Plastic shims are also stackable, fitting virtually any size joint by combining standard sizes. They are coloured by thickness, simplifying and speeding up selection and inspection. Furthermore, plastic shims will not rot or rust like wooden or metal shims, ensuring their longevity and making them a cost-effective choice.

Plastic shims are a better choice than wood or metal shims as they don't rot or rust

Plastic shims are a superior choice to wood or metal shims due to their inherent resistance to rot and rust. While wood and metal have been traditional shim materials, plastic shims have emerged as a more durable and versatile option.

Wooden shims, typically made from light, softwoods like cedar and pine, are susceptible to rotting, crushing, and degradation over time. They are commonly used to keep window frames and doors straight during installation, but their applications are limited due to their vulnerability to water, weather, and heat. On the other hand, plastic shims are impervious to water, making them ideal for various construction applications, including in-house restoration, window, and door replacement.

Metal shims, often made of steel, are prone to rust damage, especially in systems where moisture is present. They are heavier, more expensive, and more challenging to cut and shape than wood or plastic shims, making them impractical for many applications. Metal shims are also more rigid and lack the pliability of plastic, making them susceptible to movement from vibration, friction, and other forces.

Plastic shims offer several advantages over their wooden and metal counterparts. They are stronger and more dimensionally stable than wood, resistant to moisture and microbes, and will not rot or degrade like wooden shims. Plastic shims are also lighter, more durable, and cheaper than metal shims, making them a cost-effective option for construction projects. Additionally, plastic shims require little to no shaping and are available in consistent thicknesses and material properties, saving labour time and providing ease of use.

The compressive strength of plastic shims is another notable benefit. They are less susceptible to "creep" or deformation over time compared to wooden shims, providing more reliable and long-lasting performance. Plastic shims are weight-tested to 20 tons, making them suitable for heavy-duty applications. Their resilience, expressed in Rockwell Hardness and Shore D Hardness, allows them to compress under load and return to their original shape when the load is released. This property is particularly useful in glazing systems and panelized cladding systems.
