There are a lot of decisions to make when installing new windows. One of those decisions is the type, or construction, of the grilles. Also called window grids, muntins or mullions, they are available in many styles and patterns. Some are removable, while others are permanent and simulated divided light.

Aluminum bars
Aluminum is a versatile metal used for numerous products and industries. Its resistance, adaptability and cost-effectiveness make it an extremely popular material. Aluminum is also highly malleable and can be molded into various shapes. For instance, aluminum flat bars are commonly found in train frames. It is because they are about a third lighter than steel frames, which allows trains to carry more cargo and passengers while lowering transportation costs. The aluminum bar is available in round, square, hexagon shapes and hex rods. The aluminum alloys used to produce these types of bars are incredibly strong, with some able to withstand marine environments for extended periods. They are also heat-treatable to increase their tensile strength even further.
Mechanical fasteners
Mechanical fasteners are metal components that bind one surface to another. They can be either permanent or non-permanent and can be made of various materials. These are used in many applications, from manufacturing to automotive and aerospace industries. The material choice of grille clips can play a critical role in the fastener’s strength, durability, and corrosion resistance.
Some examples of mechanical fasteners include nuts, nails, screws, rivets, and pins. They can be made of various metals, such as aluminum, brass, bronze, and steel. These are often coated to protect them from corrosion and rust. They can also be made of stainless steel, which is a highly durable metal. It is an alloy of low-carbon steel with chromium, giving it good corrosion resistance and formability levels. It is non-magnetic and resistant to high temperatures. It is the preferred type of fastener in aircraft and petrochemical industries because of its durability, sustainability, and tensile strength.
Dual-lock adhesive
3M Dual Lock adhesive-backed reclosable fasteners offer a strong alternative to screws and bolts. They are durable, easy to use, and can be reopened and reclosed up to 1,000 times before losing half their original tensile strength. The product is ideal for various applications, including specialty vehicle panels, point-of-purchase displays and exhibits, and construction. It features hundreds of interlocking mushroom-shaped heads that snap together with an audible snap to create a strong attachment. It is also backed by a rubber adhesive that binds well to many plastics (acrylic, polycarbonate and ABS), powder-coated paints, and low-surface energy materials.
When selecting the correct product, it’s important to consider the environment where the Dual Locks will be used and how often they will be opened and reclosed. The right stem density combination can help achieve optimal tensile, shear and cleavage strength levels. For the best results, it’s important to apply the product to a clean, dry surface and press down firmly to ensure adequate contact with the substrate.
