Fire Proofing & Fire Protection

TBS has more than 20 years of experience in supplying a wide range of fireproofing and fire protection products including:

  • Monokote, 
  • Zonolite,
  • Kaowool

For exterior application of fire protection to steel requiring rating, TBS is an approved applicator of

  • Chartek,
  • Thermo Lag,
  • Fendolite MII;
  • and Pyrocrete 241 for petrochemical plants;

as well as most single pot intumescent paint coatings used in commercial buildings.

These materials allow TBS to provide the necessary fire resistance ratings to structural steel, roof systems, and ship bulkheads. In addition, TBS can upgrade the fire ratings of concrete slabs, partitions, and air conditioning duct work.

Pipe Wrapping

TBS has many years of experience in pipe wrapping of smaller diameter pipes in our Taranaki factory. We regularly carry out field wrapping of field welds on all line sizes, this service generally also includes the internal coating of the weld which could be cementitious or organic materials such as epoxy.

Penstock Painting

TBS has considerable experience with penstock recoating having completed multi-million projects such as the replacement the external protective lead based coating on the three penstocks that feed into the Tuai power station in Waikaremoana; and the internal coating of the Poatina Penstock in Tasmania and six penstock internal relines at Roxburgh.

We have a specialist team that typically completes two to three penstock internal relining’s or internal repairs per annum, most of which are on the Waikato River.

The quantity of work we have performed in this specialised area has allowed us to invest in equipment that provides safe access within the penstock and automates some of the processes allowing work to be executed safely and efficiently.

Metal Spraying & Thermal Spray Coating

TBS provides specialist metal thermal spraying services for various clients in both the public and private sectors. We have significant experience in the application of thermally sprayed aluminium, particularly at Refining New Zealand and have completed a variety of other metal spraying projects on the Auckland Harbour Bridge, for the Auckland Council and Creative Systems. TBS use both arc and flamespray techniques. The resultant coatings can be thicker than coatings applied using other systems such as electro plating. Thermal spraying can be used as a thermal barrier coating, as well as for corrosion protection, and to replace worn material. TSA or thermal spray aluminium coating is commonly used to prevent corrosion under insulation on steel equipment in refineries and TBS have extensive experience in this application.
