When selecting a floor hatch, it is important to consider not only the dimensions and technical characteristics, but also the material of manufacture. GROTUS products use two main options — carbon (mild) steel and stainless steel. Each material has its own characteristics and optimal areas of application.
GROTUS Floor Hatches Made of Carbon Steel
Carbon steel is widely used in construction due to its strength and affordable cost. GROTUS carbon steel floor hatches are designed for stable operating conditions and high mechanical loads.
Advantages:
high structural strength and rigidity;
optimal balance between price and performance characteristics;
possibility of additional surface protection (painting, powder coating, polyurethane powder coating, galvanizing).
Operating features:
when exposed to moisture, a protective coating is required;
periodic inspection of the surface condition is recommended.
Suitable for installation:
in dry indoor areas;
in residential and office buildings;
in technical and engineering zones with a controlled microclimate;
with polyurethane powder coating, suitable for outdoor use in aggressive environments.
GROTUS Floor Hatches Made of Stainless Steel
Stainless steel contains chromium, which forms a protective layer and significantly increases corrosion resistance. GROTUS stainless steel floor hatches are designed for demanding operating conditions and long service life without additional surface treatment.
Advantages:
high corrosion resistance;
resistance to moisture, temperature fluctuations, and aggressive environments;
minimal maintenance requirements;
long service life under intensive use.
Suitable for installation:
in wet areas (bathrooms, showers, laundry rooms);
in unheated and outdoor areas;
at industrial and commercial facilities;
in premises with increased sanitary and hygiene requirements.
Which Material Should You Choose?
When selecting a GROTUS floor hatch, it is recommended to focus on the operating conditions:
for dry indoor areas, a carbon steel hatch with a high‑quality protective coating is the optimal choice;
for wet, aggressive, or outdoor environments, it is advisable to use a stainless steel hatch, which ensures stable operation and long service life without additional maintenance costs, or a carbon steel hatch with polyurethane powder coating.
Conclusion
The GROTUS product range includes floor hatches made from different types of steel, allowing the optimal solution to be selected for specific project requirements.
Carbon steel — a practical and cost‑effective option for standard conditions.
Stainless steel — a reliable solution for harsh environments and increased operational demands.
