what

Steel has been used as a support material in buildings and structures for over 150 years. Henry Bessemer developed and patented his eponymous Bessemer process in the 1850’s, allowing steel to be produced cost effectively on a large scale.
By the 1860’s a mere 10 years late, steel was being widely used throughout the construction industry and continues to be the material of choice for structural support up to this day.

where

Steel beams provide primary support for many buildings and structures, typically falling into three main categories;

Endo-skeleton – Steel beams give support from within the building, often encased in brick or concrete.

Exo-skeleton – Steel beams are visible from the outside and provide external/integral support for secondary materials. e.g. bridges, piers

Entire – Whole structure made of steel, e.g. towers, bridges, oilrigs.
At A4W Ltd, we have a wide range of fully mobile shot blasting and sandblasting equipment allowing us to carry out works in all areas and locations from city centre rooftops to remote transport bridges.

why

Steel is made up of two naturally occurring elements, iron and carbon. Exposure to oxygen and water will cause the iron component of steel to corrode, compromising structural integrity and load bearing capacity.

Current commercial development and economic growth has led to a demand for refurbishment, renovation and expansion of both disused and currently in-service buildings and structure’s.

Replacement of structural steels can be timely and expensive, critical factors when considering any development project. Shotblasting or Sandblasting structural steel can offer an effective alternative.

In order to stop oxidation and subsequent detrition of the steel, existing rust must be removed and a protective coating system applied. Sandblasting by skilled technicians can provide accurate removal of target material from a specific area, leaving substrates keyed and ready to receive selected coatings.
Shotblasting, Sandblasting structural steel

In some instances, structural steels present themselves with a layer of fire protective paint or foam that has deteriorated or outdated its protective/intumescent qualities. In order to re-certificate for fire-protection, old coatings must be removed before a new coating can be applied.
