When the world's best expedition tent makers want lightweight alloy poles, there's only one place they go to: the DAC company.
Highly respected in the outdoor industry, DAC has spent many years inventing and refining the techniques needed to produce high-strength lightweight alloy tubing. Along the way they have developed many technical innovations and considerable expertise in design. The DAC research & design facility in South Korea now includes the world's only wind tunnel specifically for tent evaluation and design.
It was from this long history of design & innovation that Helinox was born.
Drawing on the advanced alloys developed by DAC, Helinox products bring the benefits of strong, lightweight, compact design to new fields – camp chairs, camp stretchers, tables and walking poles.
To guard against corrosion and preserve appearance, aluminium alloy components need to be anodised.
Traditionally the anodising process involved boiling alloy components in a brew of nitric & phosphoric acids.
Long before ‘eco’ became a buzz word in the industry, DAC started trying to eliminate harmful nitric & phosphoric acids from the anodising process.
After 8 years of trial and error, DAC perfected the ‘Green Anodising’ system that is used to treat all Helinox products. A water recycling program in the anodising facility further reduces environmental impacts.
The end result ensures longevity of TH72M alloy components while reducing negative impacts for both the environment and the people who manufacture your Helinox gear.
TH72M is the technologically advanced alloy developed by DAC and used in the outdoor adventure equipment industry wherever maximum strength with minimum weightis required. All the best quality lightweight tents use DAC tent poles made from TH72M.
When it comes to walking poles, camp chairs, cots & tables, only Helinox products use TH72M.
TH72M represents a major leap forward for lightweight material science – setting a new benchmark far ahead of previous standards.
DAC engineers worked closely with metal producers for several decades to develop improved alloy blends. Apart from reaching new heights of strength, TH72M broke through a development barrier that has eluded the industry for many years. The phenomenon of “stress corrosion cracking” (SCC) arises in very thin lightweight tube. The grain structure of the alloy can break down to produce a “cracking” effect - substantially weakening the material.
This meant it was necessary to produce alloy tubing with thicker walls to avoid the SCC problems. The thicker walls provided no increase in overall strength – just extra weight.
TH72M is a very strong material that is also largely free of SCC characteristics. That means TH72M can be used to produce alloy tubing that is “thinner walled” than ever before. The result is tubing that is considerably stronger (because of the superior strength of TH72M) and considerably lighter (because the wall thickness can be reduced without SCC problems).
The sucess of TH72M isn't just about the alloy formulation – that's just the start. Over 80 separate processes are needed to turn raw alloy into the finished TH72M tubing.
High specialised extrusion, heat treatment and anodising processes have been developed by DAC over many years. Specialist machinery has been designed in house by DAC to cope with the extremely high extrusion pressures and deliver ultra fine tolerances.
Now you can enjoy the benefits of all this hard work – with gear that is strong, light, comfortable and compact!
