On a metal greenhouse, the guarantee that the manufacturer offers is usually a very good indicator of the quality of the building.

The 5 years guarantee is found on 66.67% of Palram metal greenhouses [9]. It is great that this greenhouse was given one of the highest guarantees offered by the brand, and this shows the manufacturer has a lot of faith in the overall quality of this part of their product range.

When looking at comparable 6′ x 6′ metal greenhouses (we found 71 of them) the most popular guarantee length offered by manufacturers was 10 years [10]. 60.56% came with a missing guarantee, 14.08% came with a 10 year guarantee, 12.68% came with a 5 year guarantee, 7.04% came with a 12 year guarantee, 2.82% came with a 15 year guarantee, 1.41% came with a 1 year guarantee and 1.41% came with a 7 year guarantee.

Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 3 greenhouses that have options that you might find a better fit if this is a concern you have.

1. Powder Coated: Typically used to give additional corrosion resistance to steel, powder coatings can be described as 100% solid paint which comprises a homogeneous blend of polymers, pigments and additives produced in the form of a fine powder. The powder is applied on the object to be coated. The object is then subjected to heat which causes the powder to melt, flow out and form a tough, coherent film.

Almost all the paints that are used for powder coating are epoxy polyester hybrid powders, these hybrids have properties similar to those of epoxy powders, however, their additional advantage is that they have improved resistance to overbake yellowing and more importantly for a garden structure improved weatherability. The polyester also helps counteract the poor UV light properties of pure epoxy coatings where chalking will occur in an exterior environment.

According to the BCF (British Coatings Federation) they say this about the durability of powder coated products “This method is often used for large work pieces such as pipe line valves, fence posts etc. or small articles from the electronics industry. These coatings give a thick, tough film with excellent corrosion resistance and good mechanical, electrical insulation and chemical properties.” 

2. Polyethylene: Polyethylene (Low Density) LDPE, LLDPE is not commonly used for the construction of garden buildings or storage units. The most common use for LDPE is in the thin film used to cover poly tunnels.

According to data from the British Plastics Fedaration the physical properties of Polyethylene (Low Density) are that it is not very good when exposed to high heat with a maximum continuous use temperature of 65 °C. This is however offset by the outstanding Notched Impact Strength data that showed ‘no break’.
