Alroy Sheet Metals Ltd

Sheet Metal Fabrication Hertfordshire

Alroys is a sheet metal and fabrication business based in Stevenage, Hertfordshire.
 

From a small Hertfordshire workshop to our current 5,500 square foot factory, family values have always been at the heart of growing our business. Alroys started life in the late 1950s, working for local businesses using (by today’s standards) rudimentary hand tools and fly presses.

Our reputation grew and by 1961, in need of larger premises, we moved to Stevenage, Hertfordshire where we remain to this day. The name Alroys was created from the Christian names of our two founders, Albert and Roy Grist who continued to run Alroys for many years. After Roy’s retirement in the 1990s, the reins were passed to Roy’s son, David, who became managing director in 2011.

Quality
We are ISO 9001-2015 approved – the international standard outlining requirements for a quality management system. This means we’ve been externally verified as consistently providing a high quality of product and service which meet our customers’ needs. This also means that we meet all regulatory requirements. Gaining and retaining an ISO accreditation takes patience and dedication. That’s why it’s so important to us that quality is always at the heart of everything we do.

Why Choose Us?
We asked our customers this question. They told us that there were many things about Alroys which prompted them to choose us. Our experience and expertise, our attention to detail, our willingness to see projects through to the very end, among others. We’re proud to be on many corporate approved supplier lists.

Sheet Metal Fabrication

Large metal structures, such as staircases, canopies and railings, are created using fabrication techniques. Over the decades, Alroys has created many stunning structures for a range of clients.

Fabrication and welding
Alongside welding, we will also use cutting, drilling and assembly skills to fabricate your steel structure. The raw material is cut and drilled with holes or slots to create individual parts. These parts are then welded where necessary and the entire structure is assembled, either in our factory or off-site, according to your specifications.

Fabrication design, manufacture and installation
The initial stage of any fabrication project involves design. We’ve seen design briefs of all shapes and sizes, some start life on a few scraps of paper, others come to us as complete engineering drawings.  Once your concept is signed off, we proceed to the manufacturing phase and finally installation.

EN1090
EN1090 is a European standard introduced to harmonise safety and quality levels across the construction industry across Europe. It makes it a legal requirement for anyone manufacturing and selling structural steel components to only use a supplier with EN1090 marking.

CNC Laser Cutting

CNC - or computer numerical control - laser cutting is a versatile process, giving us the ability to create high quality cuts using the finest or the thickest metal. Laser beams power through the metal, vaporising it instantly, followed by jets of gas to leave a perfectly clean edge and finish.

Sheet Metal Services

Where it all started in 1951! Our sheet metal work is what we’re renowned for, both precision and large scale. If you’ve got a project in mind, get in touch and find out how we can help.

Prototyping
Mistakes can be costly to fix once we’re in production. That’s why we often recommend prototypes to customers who are trialling a new product. It’s far more economical to put your design concept to the test before committing to mass production.

CNC Punching
CNC stands for ‘computer numerically controlled’. The CNC punching process takes your design, translates it into numerical data and feeds this data into a punching machine which punches holes or shapes into a sheet of metal, creating metal parts.

Once done by hand, modern CNC punching machines are accurate to within microns and dramatically cut down production timescales, saving you money.

CNC Bending
CNC bending (or forming) uses the same technology as CNC punching. Instead of creating parts, the machines bend sheet metal (which is flat) into a desired shape.

As with punching, today’s machines are beyond compare and can produce components with several, complicated bends in minutes.

Welding
Welding is ideal for metal structures which cannot be created from one sheet of metal. Our welders expertly fuse metal together to create strong, long-lasting parts.

We use modern techniques allowing us to create durable structures from a range of metals, including fine gauge. MIG welding is ideal for thicker gauge metals, whereas we use TIG welding for those finer gauge metals where strength and integrity cannot be compromised.

Assembly
Assembly ranges from single component assembly through to more complex, complete assemblies, as well as prototypes. Each part is thoroughly checked prior to making it to the assembly line.

To facilitate assembly, we will call on a range of techniques including welding, crimping, riveting and bushing.

Metal Finishing

Metal finishing (also known as coating) has a number of applications, all designed to improve the finished product in some way. Used at the last stage of the fabrication process, finishing can be used to alter performance (increase strength or resilience), improve durability or change cosmetic appearance.

Hi David I have been meaning to email you since the frames were delivered, but have been caught up with field work lately. I am over the moon with the frames and lids and want to thank you for the excellent service you provided. They are exactly what I wanted.
