galvanising a building

Think it's around £400 but prices went up a lot at start of this month cause of a zinc tax or something. You've got to haggle them for a decent price.
£400 for structural steel seems very high to me. Would not expect more than £250+ zinc surcharge currently for say a 10t building?
The zinc surcharge is added as zinc is a commodity traded in dollars and recently traded prices of metals has increased significantly hence the galvanizers have added this surcharge to recover the extra cost. Always worth asking whether price quoted is all in or plus extras ( wedge group also add an environmental surcharge to their prices!)
 
Any recommended galvanisers in the Wiltshire area? Have a price from wedge group down at Eastleigh and they are looking for more than the cost of the steel. Only about 3 ton to do which I guess is the issue.

wedge at Eastleigh is the only plant in the area...hence higher prices!
contact Medway ( part of Joseph Ash) or Cardiff galvanizers as I think they may collect on a milk round
 
What is the one in newport like? Good?
Most UK plants are pretty good and all have to galvanize steel to BS EN ISO 1461 standard. The galvanizing process alloys the zinc to the steel so in simple terms if it looks good then it is good! Difference is generally in the service...and price!
Try Cardiff Galvanizers as an alternative....family business run by so very good friends of mine!

When you make something to be galvenized what size holes do they need in box section ? Im going to make silage sides for my grain trailer and see Franklin steel do a pick up drop off service, might try it if not to dear will save them rusting away in the winter lol.

dont galv them they will most likely distort in the dip,large areas of thin plate have a lot of stress in them and will distort in the dip tank with the heat unless you make a box section frame and fix sheeting on after
 
Agreed that best solution is to galvanize the box frame and then purchase galvanized sheet for over cladding after. Galvanizing the box section should be fine as zinc coatings are quite robust and certainly more abrasion resistant than paint. regards hole size the answer is "as large as possible" because these holes allow the molten zinc to flow through the section and the quicker this can happen the less time the steel is in the zinc and the less chance it will distort. Avoid different thickness's of steel welded together as this is the most common cause of distortion, as they heat up and cool down at different rates which can lead to the fabrication distorting.

Cheers, fek it for what they are i just paint them.

People that work at wedge worksop get paid per tonne bonus. So stuff gets chucked through. Some things get bent bad and local fabricators are constantly repairing. So take plenty of pics before .

Well thanks for the recommendation, they collected at 4 on Friday and returned it at lunchtime today (Tuesday). Tidy job although would have been better if I had chipped all the slag off properly. Not cheap but cheaper than wedge.
