Galvanizing Technical Data / Info
What is the size of your galvanizing bath?
|7.2m long||12.5m long Double Dip Length|
|1.7m wide||1.5m wide Single Dip Length|
|2.75m deep||2.5 high Single Dip Length|
Paint, oil and grease have to be removed before the galvanizing process to provide a clean steel surface to ensure good hot dip galvanizing.
Distortion cannot be ruled out during the galvanizing of any component due to expansion and contraction.
Weld every other wire in the mesh to reduce possible distortion.
Every sealed section of a fabricated structure must be vented for reasons of safety and to allow access and drainage of molten zinc. Holes should be as close as possible to the sealed end and on opposite sides of the section. The larger the hole size the better the drainage, the better the finish.
External stiffeners, welded gussets, webs on columns, beams and gussets in channel sections should have their corners cropped. This will aid access and drainage of molten zinc and a cleaner coating will be obtained.
Any material which is fabricated with black steel and galvanized steel that requires to be galvanized must be stripped back to base material.
This is to ensure that when the material is processed through the galvanizing bath the metallurgical reaction between base material and zinc occurs thus ensuring your material is processed to BS ISO 1461.
Powder Coating Technical Data / Info
Dimensions / Booth Size
|Booth Size||Maximum Working Envelope|
|4 m long||0.500 wide x 3m high|
Paint, oil and grease have to be removed before the powder coating process to provide a clean surface to ensure a good quality finish.
Every sealed section of a fabricated structure must be vented for reasons of safety and to allow access and drainage of chemicals at the pre-treatment stage. Holes should be as close as possible to the sealed end and on opposite sides of the section. The larger the hole size the better the drainage.
