FREQUENTLY ASKED QUESTIONS

Galvanised cleaning refers to the process of removing contaminants like oils, dirt, or residues from a galvanised steel surface to ensure proper adhesion and quality of the paint.

Yes, always rinse the surface with water after using any chemical cleaner to ensure that no residue is left before painting.

You can use the following cleaning solutions:

• Mild Detergent: Warm water mixed with mild dish detergent works well for removing dirt and grease.

• Acetone: An effective solvent for removing oils; be sure to use it in a well-ventilated area.

• Denatured Alcohol: Great for degreasing, it evaporates quickly after cleaning.

• Commercial Metal Cleaners: Look for products designed specifically for galvanised surfaces, which may contain phosphoric acid.

• TSP (Trisodium Phosphate): A heavy-duty cleaner for stubborn grime, but ensure you rinse thoroughly afterward.

• Wipe with Vinegar: Use a cloth soaked in white vinegar to clean the surface and remove oils and residues.

• Dry the Surface: Let it air dry or wipe with a clean, dry cloth.

Substation and transformer doors are specialised doors designed to provide secure access, ventilation, and protection for electrical substations and transformer enclosures.

Ventilation is crucial to dissipate heat generated by electrical equipment, prevent overheating, and maintain a stable internal environment, which is essential for equipment longevity and efficiency.

No, fire doors are designed to prevent the spread of fire and cannot have vents. For facilities requiring fire doors, alternative ventilation methods, such as extraction systems or wall-mounted louvers, should be used.

Substation and transformer doors are usually made from robust materials such as galvanized steel to withstand harsh environment

Yes, Stronghold offers customisation options, including door size, finish, hardware, and security features to meet specific site requirements.

Security features can include high-strength locking systems, anti-tamper designs, and reinforced construction to prevent unauthorised access.

Consider the environmental conditions, required ventilation, security needs, and compliance with local regulations. Professional installation is recommended to ensure proper function and safety.

Yes, installation must comply with local electrical safety and building standards. Always check current regulations before installation to ensure compliance.

Yes, regular maintenance is necessary to check for wear and tear, ensure security features remain functional, and confirm that ventilation components are unobstructed.

If fire safety is a concern, you must use fire-rated doors separately and incorporate ventilation through additional methods, like external louvers or ventilation systems.

Yes, they are designed to be resilient against various environmental conditions, such as extreme weather, corrosion, and UV exposure, depending on their material and construction.

Assess your security, ventilation, and environmental needs, and consult with a professional to ensure that the door configuration meets all necessary regulations and operational requirements.

Professional consultation is recommended to ensure that all safety, regulatory, and operational requirements are met, particularly in complex installations or challenging environments.

No, substation and transformer doors are not typically fire rated. Their primary function is to provide secure entry and ventilation for electrical equipment, not to contain fire.
