Two sheets of 18mm MDF on roof bars?
Quick question? Had anyone put two sheets of 18mm MDF on the roof bars and traveled a long distance? 200 miles? They weigh 80 Kgs so just about the max recommended weight.
Thanks in advance

I can't say that I have, but asked if I would do the answer would be a definite no. It's not just the weight factor but also the "lift" that would concern me.
A trailer would be a much safer bet, but (dare I ask) where does this 200 mile journey end that there's no local supply of MDF?yµ (idµ - eAµ) ψ=mψ

I've carried more sheets material on roof bars and racks than I can count over the years. As long as you have good long ratchet straps it is no issue. Your straps need to be 5.5m really and tight. If there is a finish on them, you'll need a third sheet to protect them as the straps need to be tight and you need to prevent the edges chaffing the straps also.

I always keep well clear of cars carrying anything on roof racks, accident waiting to happened, I’ve seen luggage, ladders and bikes come off, usually take the rack with them, not funny on a fast road, as for ratchet straps where are they hooked onto?- even welded hooks on top class trailers are now illegal for fastening straps to as they are not load tested and stamped, VOSA are very keen to uphold the law particularly if a third party is involved in an accident.It can when others can't,
It will when others won't,
It goes where others don't.

we live near a timber yeard and i have had 180kg of lengths on the roof for a very short distance - admitedly the roof rack made some funny noises but yes 2 sheets of ply should be a walk in the park for a roof rack.

The no no on ratchet straps on rope hooks is because of the fact that the men from the ministry have decided that the traditional claw type hook 'could' be opened up as the rope hook 'could' seperate the metal ends.
On my artic low loaders, it was the length of continuous weld that determined the actual loading permitted on any of the hooks, rings etc.
If you use a ratchet with a ring instead of a claw, there are no issues using rope hooks, apart from the ministry folk who don't know the correct interpretation of the law.

Be careful as nowadays two sheets of mdf will exceed the value of the car itself!

Out of interest I picked up 2 sheets of 18mm OSB-3 from B&Q this week which they cut to reduce the width from 122cm to 106 cm. These were put into the vehicle, with the lower tailgate up (so the number plate showed) with the sheets resting on a frame made of CLS that was slightly higher than the height of the lower tailgate (so no load was placed on the lower tailgate) and the upper tailgate was then tied down onto the protruding parts of the 2 OSB-3 sheets.

Reminds me of following a car under similar circumstances but they didn't tie the front down - me being higher up I could see it starting to flex in the wind and quickly overtook... As I passed it lifted/snapped and landed on the merc behind
