Expanded Metal Size Chart: Complete Standard Sizes Guide

ANPING METAL MESH – Professional Expanded Metal Manufacturer

An expanded metal size chart is the most important reference tool for anyone buying, designing, or installing expanded metal mesh. It defines diamond opening sizes (SWD / LWD), sheet thickness, strand dimensions, and standard sheet sizes – so you can quickly select the right product for your project.

As a leading metal mesh manufacturing company with 20+ years of experience, we provide this complete, industry-standard expanded metal size chart for galvanized, aluminum, stainless steel, and lath products. This guide includes US standard and metric sizes for all common applications.

Key Terms in Expanded Metal Size Chart

Before using the chart, you must understand these 4 core dimensions:

  • SWD (Short Way of Diamond): The shorter diagonal of the diamond opening (width)
  • LWD (Long Way of Diamond): The longer diagonal of the diamond opening (length)
  • Strand Width (SW): Width of the metal strip between openings
  • Sheet Thickness (T): Thickness of the original metal sheet

All expanded metal is categorized and named using these measurements – they appear in every size chart and product specification.

Complete Standard Expanded Metal Size Chart (US & Metric)

This is the official industry size chart used in North America and global construction, industrial, and architectural projects.

Pattern No. SWD (Inch / mm) LWD (Inch / mm) Thickness (mm) Common Uses
Lath 3.4 3/16" (4.8mm) 3/4" (19mm) 0.5mm Expanded Metal Lath, Stucco
# 1 1/4" (6.4mm) 1" (25.4mm) 1.0mm Filters, Guards
# 2 3/8" (9.5mm) 1-1/4" (32mm) 1.5mm Fencing, Screens
# 3 1/2" (12.7mm) 1-1/2" (38mm) 2.0mm Security, Facades
# 4 5/8" (16mm) 2" (51mm) 2.5mm Walkways, Flooring
# 5 3/4" (19mm) 2-1/2" (64mm) 3.0mm+ Heavy Industrial

This chart covers 95% of all standard expanded metal applications. Custom sizes are available for special projects.

Standard Sheet Sizes for Expanded Metal

Expanded metal is produced in fixed sheet sizes – the global standard is:

Sheet Type Size (Feet) Size (Metric)
Standard Sheet 4' × 8' 1220mm × 2440mm
Half Sheet 4' × 4' 1220mm × 1220mm
Lath Sheet 4' × 8' 1220mm × 2440mm

All sheets can be cut to custom size. For pricing reference, see our 4x8 expanded metal price guide.

Expanded Metal Thickness Chart (Most Common)

Thickness directly affects strength, weight, and price. Use this quick reference:

Thickness (mm) GAUGE Best For
0.5mm 26 GA Metal Lath, Plaster
1.0mm 20 GA Light Guards, Screens
1.5mm 18 GA Fencing, Decor
2.0mm 16 GA Security, Facades
3.0mm+ 14 GA & Lower Flooring, Heavy Industrial

Expanded Metal Size Chart by Application

Use this quick guide to match size to use – no technical knowledge needed:

• Stucco / Plaster Lath: 3.4 Pattern (SWD 3/16", LWD 3/4")
The only size used for expanded metal lath and stucco reinforcement.

• Architectural Facades: #2 – #3 Pattern (Medium Openings)
Ideal for building facade mesh and modern cladding.

• Security Fencing & Gates: #3 – #4 Pattern (Strong Strands)
High strength and visibility for safety barriers.

• Walkways & Flooring: #4 – #5 Pattern (Large, Thick)
Non-slip raised surface for industrial platforms.

• Filters & Vent Guards: #0 – #1 Pattern (Small Openings)
Fine mesh for protection and airflow.

Flattened vs. Raised Expanded Metal Sizes

Size dimensions remain the SAME for both finishes – only the surface changes:

  • Raised (Standard): Natural textured finish after expanding
  • Flattened: Rolled smooth – dimensions unchanged

You can use the same expanded metal size chart for both finishes.

Frequently Asked Questions: Expanded Metal Size Chart

What does SWD and LWD mean in the size chart?
SWD = Short Way of Diamond (smaller diagonal), LWD = Long Way of Diamond (longer diagonal). These define the diamond opening size.
What is the most common expanded metal size?
The #2 pattern (SWD 3/8", LWD 1-1/4") and 3.4 lath pattern are the two most widely used sizes worldwide.
Can I get custom sizes not on the chart?
Yes! We fully customize diamond size, thickness, sheet size, and material to your exact project requirements.
What thickness is best for expanded metal fencing?
1.5mm – 2.0mm thickness is ideal for residential and commercial security fencing.
Is the size chart the same for aluminum and steel?
Yes. The diamond and thickness dimensions are identical for all materials – only material properties change.
