FAQs
What is the difference between bar grating and expanded metal?
Bar grating is made from a grid of metal bars designed to support heavier loads while allowing drainage and airflow. Expanded metal is made by cutting and stretching a solid sheet into a diamond-shaped mesh. Bar grating is commonly used for walkways, platforms, stairs, and flooring, while expanded metal is often used for guards, screens, ventilation, enclosures, and fabrication projects.
What types of bar grating does AISS carry?
AISS offers bar grating in carbon steel, stainless steel, and aluminum, with multiple thicknesses and finishes available. Options include smooth and serrated surfaces depending on the application and traction requirements. Contact our Janesville team to confirm current sizes and inventory.
Should I use smooth or serrated bar grating?
Smooth bar grating works well for many general industrial applications. Serrated grating provides additional traction and may be a better choice for walkways, stairs, platforms, and areas where surfaces may become wet, dirty, or slippery. The right choice depends on where and how the grating will be used.
What is expanded metal commonly used for?
Expanded metal is commonly used for machine guards, security screens, ventilation, fencing, partitions, platforms, architectural features, and general fabrication. Its open diamond pattern allows airflow and visibility while providing strength without the weight of a solid sheet.
What is the difference between raised and flattened expanded metal?
Raised expanded metal retains the slightly raised surface created during the expanding process, which can provide additional rigidity and grip. Flattened expanded metal is rolled after expansion to create a smoother, flatter surface. The best option depends on whether your project prioritizes strength, surface profile, appearance, or ease of fabrication.
Can AISS cut bar grating and expanded metal to size?
Yes. AISS offers on-site cutting and can provide bar grating and expanded metal sized for your project. This can reduce fabrication time and help you purchase the material you actually need rather than doing all cutting yourself.
Can I buy small quantities of bar grating or expanded metal?
Yes. AISS specializes in serving customers who don't necessarily need mill-sized orders. Customers can purchase small to medium quantities, including individual pieces when available, while larger quantities and special orders can also be accommodated.
Does AISS deliver bar grating and expanded metal?
Yes. AISS offers delivery from its Janesville, Wisconsin location. Local and regional delivery can be arranged, and longer-distance delivery may be available depending on the order and applicable delivery costs. Contact AISS with your material requirements and delivery location for options.
