Projects have been completed in many varied sectors; the followings are just a selection of the industries which we have served:

1. Nuclear Power Stations and Power Generation.

2. Geotechnical applications providing slim couplers for jointing rock bolts.

3. Land Mark Bridges such as Buildings and structures all over the world including the landmark

  structures such as Taiwan 101 Building

4. High-Speed Railway and Underground Railway.

5. Airports and Terminals.

Quality is always at the forefront of our thinking. We strive to maintain the control of the critical coupler element, by manufacturing at our Asian based factory, this explains our handling and possession of the advanced CNC manufacturing facilities. ISO 9001 & CE certifications are also maintained- our management system, manufacturing service, process, and documentation procedure has all the requirements for standardization and quality assurance.

Excellent service and threading machines are based around the world from Asia to the United Kingdom, from the established and organized bases we make the service deals around the world, such as:

Abu Dhabi
United Kingdom
Hong Kong
Indonesia
India
Malaysia
Qatar
Dubai
China
 

The premier laboratories across the globe have completed the continued research into the performance of coupled reinforcement in various applications, such as:

1. Compression and tension cyclic loading of joints by AC133 June 1, 2008, CI. 4.1.2.1 & 4.1.2.2, 

  ISO 15835, CNS 2111-G2013, CNS 2112-G2014 & Code of Practice for Structural Use of Concrete

  2013 HK Buildings Department, CI 3.2.8.4

 

2. Standard slip tests to BS 8110:Part 1, Code of Practice for Structural Use of Concrete 2013 HK 

  Buildings Department, CI 3.2.8.3

3. General Specification for Civil Engineering Works (2006) Vol 2 CI.15.35

4. Fatigue testing of couplers up to 2,000,000 cycles

5. Performance of welded anchor blocks

6. Bespoke testing by our customers and project requirements

McCalls is the premier Asian reinforcement partner, we have a unique position as a manufacturer of coupled reinforcing bar systems and accessories that also process reinforcement in our home market. This combination of services means that we know that our products work; we use them every day!

McCalls started from a need to provide an economic supply of coupled reinforcement to match the developing Asian market; now this competitive cost structure is available worldwide from The UK and Europe to Hong Kong and China. Our commitment to ongoing product development and the highest possible customer service is only matched by our desire to provide a cost-effective service to your site.

Environmentally responsible manufacturing the couplers requires us to investigate ways of reducing carbon emissions primarily the saving in steel by reducing the lap joint & cutting/threading wastage yield a significant saving in steel and hence carbon emissions. 

Being the pioneer of rebar coupler manufacturer, McCalls will commit to these Ideals and Principals for developing full range of rebar coupler systems to the market needs. McCalls’s ethos is based upon the tag line 

“Experience …… Innovation …… Quality”
