Galvanizing
Hot dip galvanising has been used worldwide for well over a century because it provides a long-life, low-maintenance corrosion protection which safeguards steel from atmospheric attack.
With a number of different bath sizes at our various plants, we galvanize everything from lighting columns to bridges, fencing products to industrial flooring, structural sections to access support steelwork, and motorway guardrails to bracketry and fixings.
When it comes to corrosion protection, our dedicated and expert workforce and large and modern HGV fleet enable us to provide the highest standards of hot dip galvanising quality and service available.
Additionally, our dedication to adding value at every step ensures we deliver the optimal possible results and service. For example, we never forget that hot dip galvanising is a hands-on process - the final quality of which rests on the skill of our technical galvanising operatives.
All galvanising at Joseph Ash plants adhere to the coatings requirements of BS EN ISO 1461:2009 and BS EN ISO 9000 quality assurance specifications.

Shot Blasting
Before steel or other metals are galvanized they need to be cleaned of rust and other uneven/dirty particles using a process called shot blasting. Shot blasting cleans metal and gives it a smooth surface by firing a high pressure/high speed spray of abrasive materials onto a rough metal surface.
Joseph Ash Galvanizing uses fully approved top of the range heavy duty shot blasting cabinets as well as highly skilled shot blasting operators, to shot blast and strip all architectural and structural steel such as gates, fences, vehicle chassis, railings, sculptures, agricultural equipment, steel pipes, bridge components etc.
The shot blasting cabinets allow us to clean large metal surfaces on behalf of metal fabricators from many different industries across the UK. They are also fully approved and meet all COSSH, health and safety and environmental regulations.
With both an automatic loading and shot reclaim system, the process is an incredibly efficient and fast way to remove surface contaminants, without chemically altering a fabrication.
No other process is more suited to removing undesired layers or coatings.

Galvsafe Zinc Spray
Despite its inherent toughness and abrasion resistance, hot-dipped galvanized coatings can still get damaged or need repair after on-site alteration*. To provide further metal protection for steel parts that are altered or damaged after galvanization, Joseph Ash Galvanizing sells an own-brand galvanizing zinc repair spray called Galvsafe. Galvsafe can simply be sprayed onto fabrications from about 12 inches away, as long as the surface of those fabrications have been cleaned to remove wax, dirt, polish or grease etc.
Galvsafe was developed by Joseph Ash Galvanizing in response to many customers asking for an alternative spray to the branded products that are currently available on the market.
Galvsafe has the following important features:
High zinc content which contains 88% zinc in the dry film. (Zinc dust content conforms with BS EN ISO 3549)
Great colour match with most galvanized coatings
Good adhesion
Safe for over painting
Safe for use on products due to be powder coated after galvanizing as Galvsafe contains high temperature resins.

Added to this, we have the deepest and widest baths in the UK at Bilston and Telford, can double dip up to 18m at our Chesterfield site, and have a specialist spin galvanizing facility at Telford for your small items such as brackets and fasteners. We really can solve all your galvanizing requirements no matter the shape or size of your steel.
HOT DIP GALVANIZING
Hot dip galvanizing is a reliable and real-world proven solution for protecting steel fabrications against corrosion, extending their lifespan and reducing their whole-life cost. Galvanized steel can reliably last for over 60 years depending on environment, with document cases exceeding 00 years. Additionally, it requires little to no maintenance, making it ideal for fabrications where access is difficult or represents health and safety challenges.
Our services today protect your steel for the future.
SPIN GALVANIZING
For small steel items such as brackets, bolts, and fasteners that may otherwise get lost in the galvanizing bath, we have a specialist facility ensuring they can also benefit from corrosion protection. Instead of being hung on a jig, the items are placed into a basket before submersion in a special zinc bath. The basket is then spun at high speed to remove the excess zinc.
Spin galvanizing is available at our Joseph Ash Telford site with a basket size of 250mm diameter by 500mm long.
POWDER COATING
Powder coating is a popular choice among architects for architectural steel such as balconies and balustrades.
Powder coating is available at our Medway site, in the South East of England. Joseph Ash Medway is an AkzoNobel Approved powder coating applicator for galvanized steel and is ideally located for those in London and the surrounding areas. The site acts as a one-stop-shop, offering shot blasting, hot dip galvanizing, and powder coating all in one location, reducing the risk and uncertainty that comes with using multiple service providers and guaranteeing a consistent high standard of quality and service.
Both steel and aluminium can be powder coated at Joseph Ash Medway.
