Metal & Welds Testing

Steel Reinforcement & Steel (Metal) Elements

HTA primarily use the less destructive NDT technology for these investigations, however we will move on to exposure and breakout techniques where necessary. All backed up with over 30 years of experience.

Our Metal & Welds work falls into two main categories; first, the primary reinforcing steel itself and second other supporting metal elements. These lists are not exhaustive, but give you a flavour of the length and depth of the work we cover.


Don't believe the hype!
The only way to accurately determine the diameter and type of bar reinforcement
is by breaking out the element.


Steel & Metal Elements

Metal Investigations at Heathrow Airport by Henderson Thomas Associates - HTA

If you need to discover not only the metal type and construction details, HTA offers a complete remit of works to provide you with all the data required to move forward with confidence.

The following list is not exhaustive, however it gives a good idea of the range of services on offer, if there is something you require that is not listed please get in touch, as we will most likely be able to assist.

  • Construction Details - exposure of steel element to determine size & thickness
  • Connection Details - determining the presence of splice plates etc at connections
  • Material Type Determination - extraction of samples for metallurgical analysis
  • Steel Grade - determination of tensile strength via removal of samples
  • Metal Element Weldability - chemical analysis determining carbon equivalent value
  • Corrosion Survey - ultrasonic test methods to determine of loss of section
  • Weld Testing - ultrasonic technology, MPI and DYE Penetration for inspection and testing

Steel Reinforcement

Cladding Investigations by Henderson Thomas Associates - HTA

Determination of grade and type of reinforcement used, plus depth and pattern of reinforcement including determination of multiple layers of reinforcing steel.

The following list is not exhaustive, however it gives a good idea of the range of services on offer, if there is something you require that is not listed please get in touch, as we will most likely be able to assist.

  • Covermeter & GPR Surveys - determination of depth of concrete cover and pattern of reinforcement.
  • Reinforcement Size & Type - THE ONLY WAY to accurately determine size & type is via break out.
  • Grade of Steel - determined by tensile testing of removed sample.

Watch Concrete Reinforcement Exposure

The local removal of concrete to expose reinforcement and obtain dimensional details.
