Methods of Coating
Hot Dip Galvanizing
| Process | After chemical cleaning steel is immersed in a bath of molten zinc at about 450 deg C. An alloying reaction takes place between the steel and zinc forming several layers of protective coating. |
| Strenghts | Factory controlled process, independent of weather conditions or site variability. All edges and insides are fully protected. When the coating is damaged, it "self heals". The only coating with this property. Often described as the 'honest coating'. If it appears galvanized, it is! |
| Weaknesses | Only available in one colour. Can only be carried out in galvanizing factory, and hence restricted to bath capacity. |
| Durability | In the most severe environments about 40 years, but 60 to 130 years can be expected in normal environments |
| Cost | £7-10 per m2, dependent on weight, size and quantity of material |
| Heath & Safety | Reduces onsite issues of scaffolding, etc Factory controlled process. |
| Enviromental | Process controlled by PPC legislation. By-products of process are fully recyclable Zinc is recyclable. |
Polyester Powder Coating
| Process | After spray or dip based chemical pre-treatment, parts are electrostatically sprayed with powder and oven cured |
| Strengths | Hard, abrasion resistant, Varying gloss levels and finishes available, Good UV resistance for exterior applications, No Volatile Organic Compounds (VOCs). Varying textures and finishes available., No drips or runs like wet paint, Factory controlled process |
| Weaknesses | On site application not possible |
| Durability | 25 Years |
| Cost | £10-20 per m2, dependent on weight, size, colour, texture and quantity of material |
| Heath & Safety | No toxicity, or contamination issues, No on site congestion |
| Enviromental | No VOCs, No site contamination, Water based, TGIC free (TGIC = triglycidyl isocyanurate) |
Nylon Powder Coating
| Process | After chemical pre-treatment, powder is electrostatically sprayed then oven cured. |
| Strengths | Glossy tough coating, Outstanding adhesion, High resistance to oils and solvents Low coefficient of friction, Warm to the touch |
| Weaknesses | Cannot be over coated |
| Durability | 10 Years |
| Cost | £20-25 per m2 dependent on weight, size, colour, texture and quantity of material |
| Heath & Safety | No onsite congestion |
| Enviromental | No site contamination |
Zinc Rich Primer
| Process | Generic name for a range of primers. Can be brush, roller or spray applied |
| Strengths | Zinc metal containing gives good corrosion protection. |
| Weaknesses | Depends on paint system used over the top. (required) No self healing, etc |
| Durability | Depends on topcoat. |
| Cost | £10- 15 sq m on its own (zinc expensive) |
| Heath & Safety | Standard site issues |
| Enviromental | Standard site issues |

There she blows!
If you think galvanizing is all about, gates, railings and industrial components, then..look again!
R&C have developed a reputation for galvanizing 'works of art', the reputation has been built on the quality of the galvanizing on intricate and more often than not, delicate structures.
The whale was galvanized for and exhibition that is now in its 5th venue having been to Scunthorpe, Grimsby, Kingston Upon Thames and Dumfries prior to it's current residence at The Harley Gallery just South of Worksop. The whale did not go to Kingston as the doors were too narrow for it to fit, but we have had to carry it upstairs twice now and I wish it was not quite as big and heavy.

Let it snow
R&C have recently secured a contract with Leeds Welding to Galvanize one of their standard products.The fork mounted snow plow, whilst seasonal is invaluable when clearing freshly fallen or compacted snow.
Intricate coating on butterfly sculpture
R&C have recently completed a unique project that involved galvanizing and then an intricate powder coating of a butterfly sculpture for the Tropical Butterfly House, Wildlife & Falconry Centre in Yorkshire.Whilst the galvanizing element was straight forward the detail in the powder coating was very difficult… another first class job from Roebuck & Clarke.
R&C Finding Religion
Equaman Metal Products and local sculptor, Andy Shaw were commissioned by the academy of St Francis School to design and produce a large scale religious sculpture.Based on the St Francis of Assisi theme, the sculpture which is fondly referred to as Frank, has been created in steel.Equaman Metal Products turned to R&C to galvanize the complex and large (5 metres) sculpture.When asked why they chose R&C: ‘We have worked with the guys at R&C before and they understand the quality of finish that is needed on thin gauge steel sculptures, their quality and attention to detail is second to none, and as you can see from the finished sculpture, the result adds to the aesthetic value of the project.’

Creating the dream for local nursery school
R&C’s customer ‘Steel Dreams’ have for over 20 years been designing and manufacturing some amazing bespoke steelwork, their work may be found in the foyers and reception areas of some of the UK’s foremost venues, businesses and residences.They were commissioned by Ashbrow Nursery School in Huddersfield to realise a dream the children had.The children had designed their own School gates and Steel Dreams were tasked with the complex manufacturing of their imagery.After manufacture the complex gates were galvanized for a lifetimes protection by R&C.Afterwards the gates were painted to the original colours on the childrens drawings…a time consuming but rewarding exercise.
Ascent Precision continue R&C Partnership
Asecent Precision have announced this morning that they have won the next phase of the London Bike scheme and we will be processing all the galvanising. Because of the excellent quality & service that R&C had provided with the previous orders they have been awarded the contract.
