For over 45 years, McGregor Group has manufactured modular, redeployable structures, serving clients in defense, distribution, aggregates, recycling, and agriculture.
These steel and fabric canopies are designed for speed, resilience, and repeat use – enabling quick installation across a variety of tough environments.
McGregor’s clients – much like Galebreaker’s – rely on their structures to provide protection from the elements, shield equipment from environmental wear, create a safe working environment, and maintain operational continuity. Secure doors are a critical part of that equation to ensure their products deliver.
The challenge
McGregor Group’s structures are stocked as pre-assembled kits and shipped promptly – typically going from order to delivery in as little as 10 to 20 days.
“In defense and distribution, response time matters,” explains Ali McGregor, Managing Director of McGregor Group.
“Our customers rely on receiving high-quality structures at the right time, so durability, rapid delivery and ease-of-installation is vital, meaning component suppliers are crucial to achieving our level of service.”
The rapid response depends on reliable supply partnerships, and Galebreaker has long been trusted to deliver.
The long-standing relationship between the two companies is testament to the flexibility and efficiency of Galebreaker’s operations.
“Galebreaker’s products are dependable and robust – but above all else, speed of supply is very important for our business. What we want is a reliable structure that can be delivered quickly, especially when we get urgent calls from clients,” Ali explains.
“We’ve had calls from Whitehall asking for 10 modular buildings to be delivered the following week. Galebreaker has always stepped up to tight deadlines. Their ability to expedite supply makes a massive difference to us.”
McGregor designs and manufactures reinforced frames and canopies with open or gabled ends to support Galebreaker’s doors. These canopies typically span ISO shipping containers, creating weatherproof, multi-use workspaces. For Ali, when it comes to providing doors for his clients, it’s more efficient to trust a specialist with years of experience than to develop an in-house solution.
“We’re not in the business of making doors. Our product development team could, but Galebreaker has been making doors for a long time and is a sophisticated company – so we trust what we’re buying,” he explains.
An industrial door solution
As part of the partnership, Galebreaker provides McGregor with a bespoke, pre-cut 5-metre, Maxidoor Pro Manual in solid grey or green, for use on their commercial modular structures.
Typically ordered by distribution and military clients, the pre-cut door allows the structures to be erected quickly and easily, removing the need for on-site adjustments. Watch this 3 minute video about why the Royal Engineers use the Shield Canopy featuring Galebreaker’s Maxidoor.

Key benefits of the Maxidoor Pro
- Robust weather protection: Durable solution for protecting materials, personnel and equipment against environmental conditions. Built with Galebreaker’s patented nylon wind locks and a galvanised steel cowling to ensure wear and tear resistance
- Versatile fabric options: Available in mesh or solid fabric, offering flexibility for improving ventilation and air quality
- Safety and durability: A range of high-quality materials which are tear and rot resistant, flame-retardant, and UV-stable – enhancing safety and reducing the need for maintenance
- Fast access: Available in manual or electric options, Maxidoor Pro Electric is capable of operating at 8 seconds per meter, with push button or remote-control systems, allowing quick access
- Reliable: Rigorously tested to withstand up to 10,000 open and closure cycles, with a 10-year guarantee for long-lasting performance
From military vehicle servicing, which often involves more stringent Department of Defense regulations, to commercial truck servicing and storage, Galebreaker’s doors play a key role in helping McGregor create efficient workshops to meet evolving market, operational, and regulatory demands.
“For MOT servicing, our clients might need to fit in a rolling road, however many don’t have the space for it. That’s when they come to us for a canopy to house it underneath,”
Notable uses of the Maxidoor by McGregor include:
- UK military operations – providing shelters for vehicle maintenance, logistics, and personnel
- German military deployments – used as indoor training gyms and vehicle servicing stations
- Aggregates and recycling industries – protecting fine material stockpiles from wind and rain to meet environmental regulations
With a growing presence in Europe, McGregor is focused on delivering consistent infrastructure across borders.
“Customers we work with in the glass recycling sector, for example, want consistent deployment across multiple countries.
“We supply the same structure, same maintenance manual, and same components – including Galebreaker’s doors – across multiple sites. That type of consistency only works with trusted suppliers,” says Ali.
Why choose Galebreaker?
While he could choose any door manufacturer, for Ali, Galebreaker’s commitment to manufacturing expertise and clear communication are additional reasons behind the relationship’s longevity.
“You want to be sure you’re working with a business that knows what they’re doing. And when Galebreaker change a product design, they actually tell us about it – that alone sets them apart.
“If we ever got a call about a door from a customer, it would generally be bad news,” says Ali. “The fact that we don’t tells you everything you need to know.”
