Speaker: Mr Arnie Glausiusz : Tension Control Bolts ltd

Arnie represents Tension Control Bolts Ltd the designer & manufacturer of the most efficient High Strength Friction Grip/Pre-loaded bolting system used in steel construction. Arnie expertise is primarily related to preloaded assemblies, high strength TCBs, the installation tools ‘shear wrenches’ & Greenkote® corrosion protection. Arnie’s primary role includes providing consulting engineers and fabricators with design & technical training and liaising with many industry and sector groups. Arnie also has a broad range of construction experience on site with steel erectors – training erectors in best practices & dealing with challenges on site in bridges, stadia, high rise, towers, piling, rail & nuclear applications.

Prior to joining TCB Ltd most of Arnie’s engineering & construction experience related to ‘heavy’ lifting and movement of machinery.
Apart from bolting & engineering matters; Arnie’s interests include the preservation of heritage structures; and he is the proud owner of a ‘listed’ property built in 1657 and in need of some attention.

 

Programme Highlights

An overview of Tension Control Bolts covering the key features of a TCB, the installation advantages of TCBs as well as the application of TCBs in bridges and high rise. The lecture will also focus on  the  innovative coating Greenkote®

The presentation is oriented to consulting, temporary works, site, project & drawing office engineers & technical managers and covers high strength bolting, the installation tools and our environmentally friendly coating ‘Greenkote®’ which meets the stringent C5 corrosion rating for offshore, marine & coastal structures.

 The presentation includes a live demonstration ‘hands on’ with plates of steel – we also show and discuss various applications using with examples of bridges, high rise, general construction, rail, nuclear, power, wind energy applications as well as structures, stadia, high rise, gantries, OLE etc.

Report

Technical seminar /Webinar on the application of high strength bolts

By Ir LAM Chi-sing

 

A technical seminar on Tension Control Bolts TCB) was conducted on 15 November 2021. The speaker introduced that Greenkote® Tension Control Bolts are used around the world in steel construction. The Greenkote® TCB’s are the first choice for discerning engineers who demand the highest standards of bolting integrity. TCBs and the innovative Shear Wrench system are the lowest cost method for installing preloaded or High Strength Friction Grip (HSFG) bolts. Guaranteed tension t`ogether with visual inspection removes the likelihood of operator error and ensures engineers that connections are tightened in accordance with specifications.

 

A number of high profile landmark structures have been used and erected in such TCB in Hong Kong. Including West Kowloon District Museum - M+, Xiqu Centre, Tamar Government Headquarters, XRL-811B West Kowloon Terminus Approach Tunnel (South) and SIL (East) Admiralty Station (MTR Contract 901).

 

Greenkote is an advanced thermal diffusion coating of Zn-Al polymetallic composition. The patented process takes basic thermal diffusion to the next level of quality and durability. The coating is a technically superior replacement for zinc plating, hot dip galvanizing, mechanical galvanizing and zinc flake dip-spin. Greenkote delivers exceptional protection against corrosion and provides superior adhesion, coating uniformity, is hard wearing and completely eliminates hydrogen embrittlement issues in high strength fasteners.

 

The Bolts complied with BS EN 14399-1 & 14399-10. The speaker also demonstrated the process of fixing TCB by use of shear wrench.

 

The Greenkote processes is completely eco-friendly and does not produce any toxics or pollutants, including heavy metals and Cr6+.Metallurgically bonded, it cannot be easily separated by physical or environmental forces. In addition, the aluminium-rich inclusions dispersed on the surface serve to heal any micro fissures, cracks or porosity in the coating, while the zinc provides a sacrificial barrier against corrosion. The result is a highly uniform, conformal coating that gives exceptional protection against corrosion as well as enhanced durability and other performance advantages. The natural micro-roughness of the Greenkote surface gives it superior adhesion qualities for topcoats or paints. The speaker also demonstrated additional information on the Greenkote coating, TCBs installation & inspection methods. The seminar ended with question-and-answer session.
