14 gauge steel thickness

View 14ga stainless steel, mild steel & aluminum sheet thickness in mm and inch

Gauge, a popular measurement methodology for steel, is used across manufacturing, fabrication, and construction. It depicts the thickness of a metallic sheet, which, in turn, corresponds to its strength. 14 gauge steel thickness equals 0.0747 inches or 1.9 mm.

This measurement system lists thicknesses in millimetres or inches, relating to the gauge number. You can choose 14 gauge stainless steel thickness units aligned with application and compliance requirements. Generally, inches (Imperial unit) get favoured in the US.

While referring to the conversion charts, you might come across 14 Gage. It is synonymous with “gauge” and also a valid spelling.

How thick is 14 gauge sheet metal?

The gauge system gets preferred for steel – stainless, galvanised, etc. The thickness of a 14 gauge sheet metal varies by the type of material, its grade, and additional processing like a protective coating. For example, the figures for stainless are 0.0781” or roughly 2.0 mm, higher than sheet steel.

However, this system can also get used for non-ferrous materials. So, the 14 gauge aluminum thickness is equivalent to 0.0641 inches or 1.6 mm.

While these values are standard, buyers should check the charts shared by local suppliers or manufacturers. The absolute figures for 14 ga aluminum sheet thickness might vary slightly by geographical location.

How to calculate the weight of 14 gauge sheet metal?

Accurately weighing metallic sheets is vital for keeping project procurement and operational costs within budget. The weight (W) of 14 gauge sheet metal is a factor of its thickness and type of material.

W = Length * Width *Thickness * Specific density of material

It amounts to 3.125 lb/ft2 for sheet steel, equivalent to 15.1 kg/m2. Note that the figure will vary across kinds of steel. Case in point: 14 ga 304 SS thickness is higher, making these sheets bulkier at 3.15 lb/ft2. Galvanised sheets are even heftier (3.281 lb/ft2) because of the additional coating.

While the density of steel is 7,850 – 7,930 kg/m3, it is only 2,750 kg/m3 for aluminium. So, the weight of a 14 gauge aluminum sheet will be less than its steel counterparts: 0.905 lb/ft2 or 4.38 kg/m2. The lightweight nature of aluminium makes it ubiquitous in industrial sectors like aviation, where a competent strength-to-weight ratio is key.

How to check 14 gauge sheet metal projects

A 14 gauge stainless steel sheet is customary for metal framing in residential or commercial buildings. It has impressive strength and can endure various weather conditions. 14 ga SS also gets utilised for light fixtures and lighting circuits.

The best part is this thickness works for heavy-duty industrial projects and DIY tasks for home improvement. A 14 gauge alloy steel sheet can work for an auto repair, shop work, etc., with the necessary tools like a shear cutting machine and metal snips.

You may prefer to use other 14-gauge materials like aluminium for your project. An aluminum sheet 14 gauge performs excellently in electrical enclosures, signage, equipment like tanks and ducts, and architectural cladding.

How to protect against rust on 14 gauge steel?

Rust can impact the properties and operational life of a 14 gauge steel sheet. Selecting an appropriate grade of stainless steel is cost-effective in the long run. For example, 14 gauge 304 stainless steel can handle harsh chemical agents like oxidising acids and resist general and localised corrosion.

In contrast, carbon steel has a higher percentage of carbon that can trigger damage upon exposure to moisture. So, a 14 gauge carbon steel sheet will be less effective in abrasive conditions.

Here are some practical ways to combat corrosive damage:

  • Galvanising, i.e., applying a zinc coat, can safeguard your metallic sheet.
  • Consider electroplating or powder coating to protect the surface. The latter may use epoxy, acrylic, polyurethane, etc.
  • A 14 gauge mild steel sheet is susceptible to corrosion when untreated. We recommend using a red oxide primer, metal paint, or pickling. You may also employ mechanical grinding to remove the rust.
  • Inspect and clean the surface regularly to stop dirt and grime from accumulating. Soap and water are effective at cleaning steel surfaces.
  • Store a 14ga steel sheet in dry places, avoiding exposure to adverse temperature or weather conditions.
