What Is 3/4 #9 Expanded Metal?

3/4 #9 expanded metal is one of the most popular standard expanded metal patterns used in industrial and commercial applications. The naming convention defines the key diamond opening dimensions:

• 3/4: Refers to the long way of diamond (LWD) = 3/4 inch (19.05mm)
• #9: Refers to the short way of diamond (SWD) = 9 gauge size (standard industrial specification)

This pattern strikes a perfect balance between strength, open area, and weight, making it ideal for flooring, fencing, trailers, guards, and structural support. Our 3/4 #9 expanded metal is manufactured with strict dimensional tolerances for consistent quality.

Complete 3/4 #9 Expanded Metal Dimensions (Standard Specs)

Below is the official, industry-standard dimensional specification for 3/4 #9 expanded metal, including diamond size, strand width, thickness, and open area. These measurements apply to both raised and flattened finishes:

All dimensions are produced with a tolerance of ±0.1mm for metric and ±0.005" for imperial measurements, ensuring your project fits perfectly without modification.

Raised vs. Flattened 3/4 #9 Expanded Metal Dimensions

3/4 #9 expanded metal is available in two finishes: raised (standard) and flattened. The diamond dimensions remain identical, but the overall thickness and profile change:

• Raised Finish: Retains the original raised diamond profile; thicker profile, better non-slip surface; standard for flooring, ramps, and industrial grating
• Flattened Finish: Cold-rolled flat; smooth surface, lower profile; ideal for facade panels, screens, doors, and decorative applications

The core 3/4 #9 dimensions (LWD, SWD, strand width) do not change between finishes – only the overall panel thickness and surface texture are different.

Materials & Available Thicknesses

While #9 gauge is the standard thickness for 3/4 #9 expanded metal, we offer this popular pattern in multiple materials and gauges to suit your project requirements:

• Standard Materials: Hot-dip galvanized steel, carbon steel, aluminum alloy, 304 stainless steel
• Available Gauges: #9 (standard), #10, #11, #12 (custom gauges available)
• Finish Options: Mill finish, galvanized, painted, powder coated, brushed stainless

Galvanized steel is the most popular choice for outdoor and corrosion-resistant applications, while aluminum offers lightweight performance for trailers and architectural use.

Common Applications for 3/4 #9 Expanded Metal

Thanks to its ideal dimensions and strength-to-weight ratio, 3/4 #9 expanded metal is used across countless industries. Its balanced open area and structural rigidity make it extremely versatile:

Industrial & Construction:

• Industrial flooring and walkway grating
• Machine safety guards and equipment enclosures
• Construction fencing and barrier panels
• Concrete reinforcement and stucco lath

Trailer & Transportation:

• Trailer flooring, gates, and side panels
• Loading ramp surfaces and support panels
• Utility and equipment trailer components

Architectural & Decorative:

• Building facade panels and sunscreens
• Interior decorative screens and wall panels
• Custom metal furniture and cabinet inserts

Our architectural 3/4 #9 expanded metal is widely specified for modern building designs worldwide.

Weight & Coverage Information

Understanding the weight of 3/4 #9 expanded metal is critical for shipping, structural design, and load-bearing calculations. Below is the standard weight for the #9 gauge galvanized steel version:

• Weight per Square Foot: ≈ 2.1 lbs
• Weight per 4'x8' Sheet: ≈ 67.2 lbs
• Weight per 4'x10' Sheet: ≈ 84.0 lbs

Aluminum 3/4 #9 expanded metal is approximately 1/3 the weight of steel, making it ideal for weight-sensitive applications like boat trailers and mobile structures.
