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.
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
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.

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.
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
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 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
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.
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.
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 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 (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 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 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 (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.
