Gloves for glass or metal: which ones are the most recommended and how to choose them.

The handling of flat glass and metal sheets represents one of the most prevalent risk scenarios in industrial transformation. In these environments, a millimetric slip due to gravity or inertia of a material with sharp, unpolished edges can cause a serious accident in a matter of seconds.

Protective gloves for handling glass or metal are an essential PPE in almost all industries, providing professional protection in handling and assembly in metal, sheet metal, maintenance and repair, and work in the glass industry. This type of glove is also used in environments with a risk of cuts, dirt, moisture, or the presence of oils and fats, especially in loading and handling tasks where grip and durability are sought.

Therefore, the choice of this type of glove cannot be left to chance or limited to a generic glove. In this technical guide from Sekureco.eu, we analyze the materials, regulations, and critical coatings to make the right choice.

The mechanical key: EN 388 standard and TDM test (ISO 13997)

The EN 388:2016+A1:2018 standard is the European standard by which protective gloves against mechanical risks (abrasion, cutting, tearing, puncture, and impact) are evaluated and classified. With the integration of ISO 13997, the measurement of cutting resistance in materials that dull the traditional blade is taken into account.

To handle metal and glass safely, it is mandatory to ignore the old classification of cutting by circular blade (Couptest test) and focus exclusively on the letter of the TDM test, regulated by the EN 388:2016+A1:2018.

Sheet metal burrs, aluminum profiles, and flat glass exert high linear pressure on the fabric. Therefore, the minimum recommended levels for these applications are:

• Level E (very high risk): Supports a cutting force of between $\ge 22$ Newtons and $30$ Newtons. Recommended for metal profiles and light industrial sheets.

• Level F (extreme risk): Supports a pressure greater than $\ge 30$ Newtons. It is the mandatory standard for handling large formats of flat glass and feeding heavy stamping presses.

Anatomy of the yarn: What fibers stop cuts?

A traditional leather glove cannot stop the sharp edge of glass or a metal sheet under pressure; it requires composite yarn technology. The most recommended gloves use combinations of:

• High-density fibers (HPPE and aramids): fibers such as high-performance polyethylene (HPPE) or aramids (like Kevlar®) offer a lightweight, flexible structural base with excellent thermal resistance.

• Stainless steel cores: level E and F gloves intertwine textile fibers around stainless steel microfilaments. Upon impact from the edge, the steel physically blocks the penetration of the sharp edge.

• Fiberglass filaments: provide enormous resistance to static shear, absorbing cutting energy from sliding before it reaches the skin.

The ideal coating according to the work environment

The fiber stops the cut, but the outer coating determines the grip, precision, and durability of the PPE according to the conditions of the piece:

A. For glass handling (dry or wet environments)

• Recommendation: rough or vulcanized latex.

• Why: clean glass is slippery. Rough latex offers the highest coefficient of friction on smooth and polished surfaces, acting like a mechanical suction cup. Additionally, if the glass comes from washing or outdoor storage areas, it repels water excellently.

B. For metal handling (oily environments or with cutting fluid)

• Recommendation: sandy nitrile or foam (Microfoam).

• Why: sheets and metal parts often incorporate protective oils, hydraulic fluids, or machining cutting fluids. The nitrile in foam finish acts like a microscopic sponge, displacing the oil film to ensure a firm grip and prevent the piece from slipping.

Frequently asked questions about gloves for handling glass or metal

What is the minimum EN 388 cut level required for handling large format flat glass?

For handling large format flat glass, the minimum mandatory safety standard is Level F under the TDM test of the EN 388:2016 standard. This level ensures that the composite fabric of the glove can withstand extreme linear pressure and sliding equivalent to a force greater than 30 Newtons, preventing accidents caused by the weight and inertia of the glass itself.

Why is rough latex coating specifically recommended for the glass industry?

The rough or vulcanized latex is the ideal coating for glass due to its very high coefficient of friction on smooth surfaces. It works by generating a mechanical suction cup effect that prevents glass sheets from slipping from the hands. Additionally, it offers excellent waterproof resistance if the material comes from washing or outdoor storage areas.

What is the best coating for cut-resistant gloves in metallurgical workshops with the presence of oils?

For metallurgical environments where sheets or profiles contain protective oils, hydraulic fluids, or cutting fluids, sandy nitrile or nitrile foam (microfoam) coatings are recommended. This finish acts like a microscopic sponge that displaces the liquid film from the surface of the metal, ensuring a secure grip and preventing the piece from slipping.

What elements make up the yarn of a glove with TDM E or F protection level?

Level E and F gloves use a complex technological yarn. This support combines high-performance fibers (HPPE or aramids) intertwined internally with stainless steel microfilaments and fiberglass filaments. This internal structure is responsible for dissipating impact energy and physically blocking the penetration of sharp edges.

Can a traditional leather glove be used for shearing or metal stamping work?

It is not recommended. Although leather is excellent at resisting abrasion, it lacks the internal structural protection to stop a cut from sliding under the pressure of a sheet burr. Additionally, thick leather gloves drastically reduce flexibility, causing muscle fatigue and tempting the operator to remove the PPE.
