Extruded Aluminum Supplier

That is very hard to visualize. Some sketches could help immensely.

Hi Tornado,

This is about the best I can for now. I don't have the right gear to produce something better, only a piece of paper and a camera.

The preference goes to rectangular box profile (pipe) as smooth as possible on the outside. On top of this comes the prefab wall.

Thanks for the reply. D

They certainly can make it. Thanks for the link. I asked for a quote now.

However, I will "only" need about 400 Feet. G.A.

There are structural profiles that we sometimes use in machine building made by a company named ITEM. Try their profile 8 light range. There are heights of 160, 200 & 240mm and widths of 40, 80, 120, & 160mm. There is also an aluminium capping that can be applied to any unused external slots to eliminate dirt traps. It is a very comprehensive range and your whole clean room could be constructed using just their profiles, including plastic beading profiles to mount the glass panels. They have several distributors in the US.Further details on line.

Square and rectangular sections are not usually called pipes; square or rectangular tubes instead. Even the latter terms seem to be giving way to HSS = hollow structural shapes/sections. These other terms might help in Web searches.

I will check my usual supplier's Web site http://www.alascop.com/ to see what they normally stock, hoping that something useful will turn up.

2.5 x 3.5 x 0.218*
3 x 4 x 0.190, 0.250
3 x 5 x 0.188
3 x 6 x 0.188, 0.250*
4 x 6 x 0.250*
4 x 8 x 0.250

Usually in sharp corners, but * available with radius corners.

Thank you so much. Especially for the correct item name. G.A.

This is problematic when different from the native tongue. The sizes, you have found I came by also, even in .125 wall, except the 4 X 8, which is the only one high enough. But with .250 wall this will be a very expensive solution, also to cut the holes out for the filters. I wonder if maybe an extrusion for 500 Feet will be economic? The advantage is that we can "model' and reinforce it a little. Rgds. D

D,

Have you looked at 80/20 ?

Misumi sells Hepa units with mounting to extrusion. Might be worth a look even if just for ideas.

Talk to refrigeration walk in box rooms supplier. Properly assembled they are air tight. They have 4-6" insulated walls. You can have either aluminum or stainless cladding. The manufacturer can custom design the whole assembly. It is very easy to install anything you wish, as the cladding is very thin.They could probably make the openings you require. If you have some equipment weight problems the supplier can assist in suppling reinforcement for the box ceiling.

I have done this a the University of Toronto.

Could you consider two 2 x 8 x 0.125 laid back to back, with some holes in the adjoining webs to allow better lengthwise air flow?

Besides extrusion, coiled sheet could be roll-formed and welded into long pieces. I have no idea about the set-up economics for this, though.

As you see on the sketch: on top is a 6 cm profile (almost square) that can be used as top of the box joint - screws and glue or caulking. Two C channels of 2 X 8 can be put

together open side towards each other too. I guess this might save us time to assemble. The floor base is hardwood, so in the openings for the filters we can screw it all in place. Of course, best would be a rectangular tube. Thanks for thinking with me.

It is incredible: when you type in something, how the Chinese dominate the net with best places. I am looking now on Thomas net.

Hi All,

I found a supplier in Florida.

EMS - eastern metal supply.

These guys carry the most extensive stock I ever met.

Thank you all for your help.

What configuration did you ultimately settle on?

3 X 10 X 0,125

I asked for a sample, because I still need to test the load capacity and deformation of the longest side. If it is too weak, I will go for 0.166 thickness. However, the price is about to double for the latter. D
