FAQs

What types of doors can be fitted to a shipping container?

We supply high-security steel personnel doors specifically designed for shipping containers. These can be single or double leaf, fully insulated, and fitted with advanced locking systems. We also offer options such as fire-rated doors, double doors for larger access, and bespoke finishes to suit your container conversion project.

Are container personnel doors secure enough for GB business use?

Yes. Our container doors are built from galvanised steel, feature a 10-point locking system, anti-jemmy studs, and a 5-lever euro cylinder for maximum protection. They meet or exceed common GB commercial security expectations, making them ideal for offices, workshops, and secure storage units. 

Can you install container doors and windows before delivery?

Yes – all our doors and windows are professionally fitted prior to delivery. This means your container arrives ready to use, with no need for additional site work or modifications. 

Do container doors and windows meet GB building and security standards?

Our doors and windows are designed to meet GB security requirements and are manufactured from high-grade materials for strength, insulation, and weather resistance. If your project requires compliance with specific building regulations, we can adapt specifications to meet them. 

What size are standard shipping container windows?

Our standard high-security container windows are double-glazed and measure 900mm x 900mm. We can also offer alternative sizes and layouts depending on your container’s intended use and design.

How secure are container windows with anti-vandal shutters?

Very secure. Each window is fitted with steel external anti-vandal shutters that can be locked from the inside. This makes them extremely difficult to force open and ideal for sites where security is critical. 

Will adding doors or windows affect the structural strength of my container?

No – when installed by our experienced team, we reinforce the container around the new openings to ensure it remains structurally sound. This is a key reason to use a professional container modification service. 

Are container doors and windows weatherproof for GB conditions?

Yes – all our doors and windows are built to be weatherproof and can withstand heavy rain, wind, and cold temperatures. Doors are fully insulated and fitted with thermal seals to help maintain comfortable internal conditions. 

Do you offer insulated container doors and double-glazed windows?

Yes. Our standard personnel doors are fully insulated, and our container windows are double-glazed to reduce heat loss, improve energy efficiency, and provide sound insulation.

Do you deliver and install nationwide across GB?

Yes – we supply and install container doors and windows nationwide, including London, Birmingham, Manchester, Leeds, Glasgow, and surrounding areas. Our team can deliver directly to your site and ensure everything is fitted to your exact specification.
