Our engineer is building a mezzanine floor so that they will have extra storage in what would otherwise be dead space.
He has asked me what height the barriers/railings and toe boards need to be. I assume that they would be 900mm/1000mm, the same as stair rails. I'm unsure about the toe boards, tempted to have the whole thing filled in with no gaps.

If anybody knows of any documentation that I should read so I can be absolute with my facts.

Thanks

Hi Tony,

The product in discussion is one that is being designed, built and used in-house. As it isn't being sold or distributed does this still require a coded welder and a CE mark?

Thanks Tony

Yes, you could sell the building with mezzanine in the future or another company takes you over and does it.

Tony - do you have more info on this or point me in the direction of obtaining such info (thanks)? i am not in the structural steel industry, nor welding of such, but its always useful to know this kind of info

I am far from convinced that thsi needs to be CE marked. The requirement for CE marking relates to construction products placed on the market, which apparently does not apply here.

If the organisation employs a fabricator, then the steelwork will need marking, but taht will be the duty of the fabricator. If they literally design, fabricate and install it themselves then I'm not convinced, because it's not at any stage a product placed on the market. Of course, they may then breach some other rules - if they aren't competent to design, fabricate etc the structure, for example.

It is clearly not the case that all newly fabricated or erected steelwork in the UK must be compliant to BS EN 1090 and consequently CE marked - if I put up some shelves in my garage that I've designed myself and slapped together with some steel angles I had lying around, I would not be committing an offence. The problem is all the guidance I've seen assumes it is addressing either an organisation carrying out the business of designing, fabricating or supplying steelwork, or an organisation or person purchasing steelwork (or design) from such an organisation. If that assumption isn't true, the sweeping statements in teh guidance don't necesarily apply.

Regrading guidance, you could read http://www.steelconstruction.info/CE_marking or http://www.steelconstruc...ruction+-+CE+Marking.pdf

There's also http://www.constructionp...ion-products-regulation/ and the document you can download from that page, but that's even more manufacturer/supplier–centric

Hi Achrn

My point is that it could be placed on the market at a later date. Same as designing inhouse tools, which could end up on the market at a later date.

It is some time since I read the steel construction info regarding BSEN 1090, I admit and there were a number of different classes. Happy to be shown to be wrong though, that is what the forum is for, debate.

No, because a building is not a construction product. So the mezzanine within the building is still not a construction product placed on the market, even if the building is on the market.

Again, however, I caveat that while it may not need CE marking (in my opinion), there's a lot of other requirements that it will need, and I'm not sure an organisation that doesn't normally design fabricate or erect structural steelwork will find it easy satisfying all those. It probably depends whether this mezzanine is more akin to some shelves or more akin to a whole new building floor. From memory, there have been HSE prosecutions where an organisation installed mezzanine structures for lightweight storage, and then started using them for office space or heavier storage, leading to collapse.

Our mezzanine is going to be used for storage, it will be constructed from some seriously heavy duty metal work too.

My engineer is a vastly experienced guy, but we do have all all the work assessed by a structural engineer so that we can sign it off. I assume that the metal work we buy in for this purpose will be CE marked as a result of the aforementioned changed to legislation.

The components you buy in probably will be CE marked. The basic sections you buy in probably will be CE marked. If you fabricate it yourself from those components, the fabrication will not be CE marked (unless you get it so, obviously, which will require you to do the fabrication in accordance with various execution standards, though it would arguably be a good idea to do it in accordance with recognised execution standards anyway). If you got the frame fabricated by an outside party then the fabricated frame would be CE marked too.

The way the regulations have been interpreted in the UK is that the steel frame as a whole, fabricated and sold to you as a fabrication, should be CE marked as well as all the bits that went into it. It's an arguable interpretation, and strangely the industry seems to have reached a different conclusion with respect to some precast concrete components. I personally can't see how the directive clause that is held to exempt certain precast concrete elements cannot also be used to exempt one-off bespoke steel frames, but the industry has decided it doesn't, so that's how it is.

I went back and had a quick look and you are right it only seems to cover you if you are actually trading in the items. It didn't actually say anything that I found about self fabrication. It does seem like a very big loophole though. If this is correct then there seems to be nothing stopping you fabricating and erecting an entire structure without meeting these standards, then selling it at a later date (provided that is not the business you are in).

Free building with every cake you buy ! :0)

Very interested in this. If a mezzanine installer fits a new steel mezzanine into an existing store am I right to assume that all the steel has to be CE marked ?

Does the same apply to a steel staircase?

If there is a harmonised european standard covering staircases, then yes. The list of standards is at http://ec.europa.eu/ente...on-products/index_en.htm but it takes some ploughing through to decide what each covers, and it might depend on the type and application of the staircase.

In general, fabricated structural steelwork is under harmonised standard EN 1090, so is covered and should be CE marked.

I imagine its another function to show compliance from a building warrant point of view.
Or a money making scheme?
