The Anchors Division
Over 30 years experience.
Design, manufacture, supply and
installation of comprehensive range of
refractory anchor systems for
monolithic, ceramic fibre and brick
refractory linings; temperatures up to
1600°C.
Team ensures correct grade of material,
dimensions, spacing patterns and
welding methods are selected for an
anchorage system; this is essential in
enhancing the lining performance.
Refractory Anchor Manufacturing Facilities

Refractory Brick Anchors
Complete range of high quality standard and custom-made refractory anchors for refractory brick linings
Ceramic Fibre FixingsThe company offers several systems suitable for anchoring ceramic
fibre over a range of temperatures including the following.
Press On Clip Systems
Threaded Studs
Washers
Wide range of Ceramic Fibre Fixings
Ceramic Fibre Fixings
Lock WashersModule Backing Plate Fibre lock pins
Hex Mesh Anchors • For process plants which is subject to the passage of erosive gas streams, especially at
high temperature.
• Supplied as flat panels or rolled shapes.
• Temperatures up to 800° C.
Reinforcing Fibers - Melt Extract
• Range of Melt Extract (ME) reinforcing fibres for standard industrial use through to specialty applications such as extreme temperature, high corrosion and niche industry requirements.
• Steel fibres for mining and construction industries.
• The use of our stainless steel alloy fibres substantially improves refractory durability and performance, and reduces refractory installation maintenance and material.
Shear Connectors
• Cost savings: reduction of building materials in the designof composite structures.
• Reduced building heights: save on materials as lighterbeams result in shallower floor sections.
• Secures concrete to steel structural components.
• Increase shear loading capacity in steel buildings.
• Provides larger rooms with fewer obstructions becauselonger beams can be used.
• Reliable and safe under static and dynamic stress.
• Mechanical interlock of steel and concrete.
• Firm welds produced by stud welding.
• Application by trained operators – no highly qualifiedwelders required.
An essential component in steel-concrete composite
structures, beam design and construction. Composite
construction combines the positive features of steel
construction and structural concrete thereby offering the
following benefits:
Wear Studs and Spike Studs
• Wear studs used in earth moving and mining construction equipment.
• Spike Studs used in the timber industry.
CD Pins and Clips
• Fastening systems that are ideal for stud-welding fasteners for heating,
ventilation and air-conditioning, signage and construction industries.
Stud Welding
Studwelding Equipment
• Leading stud-welding technologies from Taylor Stud Welding Systems Ltd (United Kingdom) and brands, including Taylor (UK) and Heinz Soyer Bolzenschweisstechnik GmbH (Germany).

Why Stud Weld Refractory Anchors
Limitations of Conventional Methods of Installation Stud Welding Properties
Drilling and tapping: These processes are slow. The
system also requires thicker parent material and longer
studs
The process is fast (up to 30 studs a minute) as the entire
arc welding cycle normally takes less than a second.
Inserts: These can work loose. Holes must be punched
and deburred, weakening parent material and taking time.
The reverse side is not always clean and flat.
There is minimal heat and penetration depth, preventing
distortion and ensuring good attachment to thick and thin
materials (from 0,7 to over 2,0 mm).
Back welding: The process is slow. Holes need to be
punched and deburred in parent material, which weakens
it. The excess weld has to be ground off to achieve a
clean flat finish.
No holes are needed eliminating the possibility of leaks or
weakening of the sheet. The stud welding equipment is
portable and easily jigged.
Through bolting: Requires two-handed assembly with
access from both sides. Holes need to be punched and
deburred taking time and weakening the parent material.
the assembly is not leak-proof.
There are a variety of stud welding processes suitable for
securing studs ranging in diameter from 1,0 to 30 mm.
The weld is stronger than the parent material or the stud.
Access is required from only one side.
