The modern scaffolding industry owes its very existence to the vision of one man, Daniel Palmer-Jones, the founder of SGB. In fact, the history of the industry is virtually that of SGB. A history of constant innovation and achievement resulting in a range of products that have become industry standards.
In 1909 Palmer-Jones was granted Patents for the 'Scaffixer', a coupling device which was to revolutionise scaffolding construction. The Scaffixer soon became the accepted industry standard coupling and in 1913 was used exclusively in the reconstruction of Buckingham Palace.
This milestone invention was followed in 1918 with the 'Universal Coupler' which would still be familiar to scaffolders today.
1920 saw the introduction of Tubular Steel Scaffolding, a complete step change in an industry which had been based largely upon timber and another example of the foresight of Palmer-Jones.
1944. The very first Frame System was brought to the market by SGB, its timely introduction providing a valuable tool in the many and massive construction projects following the Second World War. 
1949. The introduction of Simon Hydraulic Platforms captured the attention and acclaim of the industry and SGB continued to
expand into new markets.
1959 saw another first with the introduction of SGB Shuttering, the forerunner of today's Formwork and the company's global record of formwork and shoring services in some of the world's most ambitious construction projects.
1966 brought the introduction of the Tableform System, followed only two years later by the Metriform small formwork panel system which has sold more than 3 million units.
1975. Aluminium Towers are introduced, a product which has revolutionised access for the small builder. 
1976. Cuplok Scaffolding, a major design innovation, was first brought to market and is one of the world's most widely used system scaffolds.
1988 and SGB introduces temporary mesh fencing to the UK, yet another product which has become an industry standard. Developments in fencing continue with low level barriers and the new long life plastic base unit.
1996. The Boss Aluminium Tower is the first tower system designed specifically to the new British Standard. It quickly becomes No.1. 
1997. GASS is launched, a new generation aluminium shoring system which is already in demand even before its official launch to the market.
1998. Cuplok 3000, offering more in-built safety features and longer bay lengths is introduced to the market.
1999. SGB became established as a major national supplier of Powered Access Equipment.
1999 The new Logik Panel System for Formwork is introduced, offering both Crane and Hand set panels.
2000 SGB is acquired by American company Harsco Corporation. The acquisition gives the Harsco Corporation the opportunity to widen its geographical spread into the UK and Europe through the established SGB businesses
NOTE: This history was taken from the SGB website, hence the SGB focus on many of the dates. Interesting to read tho....
