Rungs and rails are crimped together with
new crimping technique in order to
- fasten production cycle 
- improve precision of crimping process 
- reduce deformation of aluminium rungs 
- increase resistance against torsion 

Rungs are covered with polyamid caps

-	strong and flexible
-	to protect the rung
-	to protect the operator

Spring loaded bolts/locking pins
- are made of polyamid - Nylon 
- reinforced with galvanized steel 

Welded rungs
Sliding parts of CountryStep are welded. Today, aluminium welding is one of the most frequently used bonding techniques for light alloys. All alloys can be resistance welded and, apart from a few composite materials and a few foundry alloys, most of them can be inert gas arc welded. 
Rungs of sliding ladders are welded with MIG-method (Material Electrode Inert Gas method). Rollers push the aluminium wire inside the torch until it reaches the arc where it is melted and deposited. 

Welding quality
The strength of a welding depends on 
- the type of basic alloy 
- the geometry of the bond 
- the deposited material 
- the precision of the technique and 
- the heat control 

Welding quality control is guaranteed by
- 6 axis welding robot 
- intelligent welder inverting program 
- fully electronic absolute position detection 
- digital servo mechanism 
- 100% sight inspection. 

Ladder shoes
- Shoes are made of polivinilchlorid (PVC) 

Packing
- The ladder is packed in 0.03 mm, shrinked transparent polietilen foil (PET).
