Our verdict on the Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House

The Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House is treated using a galvanised process [1].

Base material: steel [2]

Our experts say this has 1 stand out feature. A stand out feature is something found on over 70% of the top 10% of products in a particular category or is an exceptionally good feature as rated by our panel of experts.

1. A galvanised treatment like the one used on this greenhouse is one our experts are happy to say is one of the best around.

Below is a brief overview of how some of the key points of this greenhouse fairs across the market.

Treatment

Great, our experts say most of the treatment options used are among the best.

The galvanised treatment process used here is the best type of treatment out of 2 [3] types we’ve identified on same-size greenhouses that you’ll see getting used on 17% [4] (137 of 787) of all greenhouses analysed, as well as being used on 23% [5] (18 of 78) of the top 10% of greenhouses. While you’ll find that the Expert Score of this greenhouse is 3 points lower than the average for galvanised 9′ x 11’s (87 vs the average of 90 [6]), you can be sure it’s not due to the treatment as this one of the highest scoring treatments found on 9′ x 11′ greenhouses. You’ll also find the galvanised treatment showing up on 14% of 9′ x 11′ greenhouses (5 in total).

In fact this is the only 9′ x 11′ greenhouse you’ll find that uses a steel wall [10].

The Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House has an Expert Score that is 15% higher than average and is £961 less expensive than average. If you are looking for the best value or highest expert scoring greenhouses out of the 15 with comparable specifications the following might be of interest.

Best value – If you are looking for something comparable that costs less, then you could save £1 with this 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent. It is priced at £399, this is 329% more than this and has an Expert Score of 90, 2 points higher than the Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House.

Highest Expert Score – With an Expert Score of 90 vs 87 for this product, the 8’x12′ Palram Canopia Bella Large Walk In Silver Aluminium Framed Greenhouse is the best 9′ x 11′ greenhouse with comparable specifications, and is priced at £1,099, that’s £1,006 more than the Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House.

High Wind Area – If you live in a particularly exposed or high wind area then having a greenhouse with a thicker cladding and higher than average frame thickness can be preferable. We found at least 2 greenhouses that have a combination of features that can make them more suited to higher wind areas.

Coastal Consideration – If you live in a particularly wet or harsher environment such as by the coast then you might want to consider something with a more robust pressure treatment or something made from metal or plastic, both materials that are particularly suited to such harsh environments. We’ve found at least 3 greenhouses that have a combination of features that can make them more suited to higher wind areas.

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.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.

1. Galvanised: Galvanising steel or Zinc Galvanised steel as it is sometimes called refers to the process where steel is immersed into molten zinc. This is where a series of zinc-iron alloy forms a series layers via a metallurgical reaction between the iron and zinc, providing a robust coating which is an integral part of the steel.

Galvanised steel is among the most corrosion resistant due to its sacrificial protection and self-repairing properties. According to the Galvanizers Association they say “Hot dip galvanising offers coverage both externally and internally within hollow sections, it self-repairs when damaged, sacrifices itself to protect the base metal, is environmentally sustainable, has good impact and abrasion-resistance and a maintenance-free life of 50 years or more. Galvanised steel is widely used in applications where corrosion protection is needed and can be identified by the crystallised pattern on the surface (often called a ‘spangle’).” 

2. Steel: Is the “world’s most important engineering and construction material” according to the World Steel Accosiation. When it comes to garden structure steel is often a very strong and durable metal, although if it is untreated then it is prone to rust and corrosion. Steel is an alloy of iron mixed with less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. When steel comes into contact with water and oxygen there is a chemical reaction and the steel begins to revert to its original form – iron oxide (that’s Rust to the layperson). Steel must be coated in a protective layer to stop this reaction, for most garden applications this consists of powder coating or the more stable and long lasting use of galvanising the steel first.
