20 x 1600 Lumber Size Guide and Common Applications
Learn how to work with 20 x 1600 mm lumber, compare material options, convert measurements, and explore common woodworking and DIY applications.
Introduction to 20 x 1600 Measurement
If you are planning a construction, woodworking, or DIY project, knowing how to work with 20 x 1600 materials can make a big difference in precision and outcome. This measurement, most often expressed in millimeters, typically denotes a 20 mm thickness by 1600 mm length — though in some disciplines, such as metalworking, it can signify width × length.
These proportions are common for boards, planks, and flat stock, delivering a long, narrow profile perfect for trim, slats, and reinforcing strips. Understanding exactly what the numbers mean in your context helps you choose the right material and ensures a proper fit for your project.

Common Materials Available in 20 x 1600 Size
While 20 x 1600 sizing is widely associated with timber products, it is available across multiple materials, giving you options tailored to strength, appearance, and durability:
- Wood: Pine, oak, birch, MDF (Medium Density Fibreboard), and plywood.
- Metal: Aluminum flat bars, steel strips, and galvanized sheet sections cut to these measurements.
- Composite: Fiber-reinforced plastic, composite decking planks, and engineered timber.
Selecting the right option depends on your specific use-case and environmental factors.
Quick Material Comparison
| Material | Strength | Durability | Common Use |
|---|---|---|---|
| Solid Wood | Medium to High | Moderate | Furniture, Interior Trim |
| Plywood | High | High | Cabinets, Subfloor |
| Aluminum | High | Very High | Frames, Outdoor Fixtures |
| Composite | Moderate | Very High | Decking, Exterior Panels |

How to Read and Convert Metric and Imperial Measurements
The metric dimension 20 x 1600 mm is equivalent to approximately 0.79 x 63 inches in imperial units. Conversions are crucial when your project specifications differ from supplier listings.
Conversion Formula
To convert millimeters to inches:
inches = millimeters ÷ 25.4Example:
20 mm ÷ 25.4 ≈ 0.79 in
1600 mm ÷ 25.4 ≈ 63 in
Be aware that nominal lumber dimensions (e.g., “1x4”) differ from actual measured size, so always check actual thickness, width, and length before substituting materials.

Typical Applications in Construction, Woodworking, and DIY
Because of its long length and slim profile, 20 x 1600 stock can be applied in various ways:
- Trim and Moldings for doors, windows, and baseboards.
- Slats or Panels for furniture backs, shelves, or decorative walls.
- Structural Strips for joint reinforcement and framing.
- Framing for Light Fixtures such as LED installations.
- Outdoor Projects including garden edging and trellis work.
Its versatility suits both decorative and light-load structural purposes.

Factors to Consider When Choosing 20 x 1600 Material
Before purchasing:
- Strength – Will it carry weight or withstand stress?
- Durability – Is it moisture-, insect-, or UV-resistant?
- Finish – Smooth for painting/staining or textured for grip?
- Workability – Ease of cutting, drilling, and joining.
- Cost – Factor in price per length and waste from cutting.
For outdoor use, choose treated wood or composite; for indoor shelving, MDF may be more cost-effective.

Cutting and Handling Tips for 20 x 1600 Pieces
Long materials need careful handling to avoid warping or damage.
Cutting Recommendations:
- Work on a stable, long bench or sawhorses.
- Clamp securely at multiple points.
- Measure twice, cut once.
- Use blades suited to your material (carbide-tipped for aluminum; abrasive discs for steel).
Handling Tips:
- Carry with a helper or balance at midpoint if solo.
- Use padded gloves to protect against sharp edges.

Maintenance and Care for Longevity
Regular upkeep ensures longer life for your 20 x 1600 components:
- Wood: Seal with varnish or paint; store in dry conditions.
- Metal: Inspect for corrosion; apply anti-rust treatments.
- Composite: Clean with mild soap; avoid abrasive tools.
Inspect outdoor installations seasonally for weather damage.

Safety Considerations When Working with Large Dimensions
Working with long, thin stock has unique safety concerns:
- Eye Protection against sawdust, splinters, and metal filings.
- Gloves to prevent cuts.
- Hearing Protection during extended cutting.
- Clear Workspace to avoid snagging boards on obstacles.
Prevent bending and sudden movement by carrying securely with adequate support.
