Auto & Vent Louvers

We manufacture all types of Louvers for all types of cars and any other ventilation purpose to specially to suit a customers request.

We also have a small range of "Stock Louvers" which we are hoping to increase range and these can be purchased from our online shopping cart, by phone or email etc. 

These Stock Louvers can be used for automotive purposes or for other ventilation purposes, such as cooling food vans, caravans, truck trailers or industrial equipment etc. So our louvers can also be used for other general purpose ventilation.

All louvers are high quality and look terrific. We have great response from customers about our car louvres.

Our louvres can be used for automotive purposes for cooling engines or other ventilation purposes, such as food vans, caravans, cooling of industrial equipment and truck trailers etc.

We manufacture louvres from a range of metals such as aluminium, steel and stainless steel.

We make double sided louvers and single sided louvers, louvers which face forwards and backwards on the same panel and also triangular shaped louvers.

We manufacture different styles of curved profiles and can manufacture louvers with different opening distances.

Our louvers will suit motoring enthusiasts who are restoring antique cars and want them to look their best and also people wanting modern car bonnets where louvres can improve a cars appearance.

We work in conjunction with supplying many car restoration businesses with our automotive louvers.

We now have capacity to press very wide louvre panels up to 2 meters wide and any reasonable length which is now available  And we now have the capacity to press whole existing bonnet panels.

We currently offer individual louver widths in our standard louver tooling in 15mm wide and 25mm wide up to 400mm long and in 1mm and thick steel (overall panel widths can now be up to 2 meters wide - 2000mm maximum width).

But we have recently added our VW Kombi Louver panels which have 515mm long individual louvers.

We can do any spacing of louvers as long as there is at least about 25mm to 50mm gap between rows (we can make narrower gaps but depends on job etc..but there should 25mm minimum gap so doesnt interfer with tooling). And we normally need about 20mm minimum material around outside or sides of the louvers themselves. Larger widths (greater than 400mm indiv louvers) available on request. We offer various louver styles which we will be showing customers on website soon

(Please note the prices for our stock louvres are for production louvres. Special custom made, one off or prototype louvres which require custom tooling and design work will have varied very reasonable prices to suit, depending on numbers and complexity)

****Also NOTE that some ordered louvres may be too big to fit inside next day express post satchels so please allow 3-4 days delivery time by Parcel Post.

 

Speedex Louvre General Terminology

We decided to draw a simple picture above to show customers what our Speedex General Louver Terminology is when describing or specifying a particular louver requirement to us.

LENGTH = Length of an individual louvre opening

WIDTH = width of each individual louvre

DEPTH = Depth or opening height of each individual louvre

PITCH = Spacing between each individual louvres

MARGIN = distance between side of a louvre to perimeter of panel itself. And also between rows of adjacent louvres side by side etc.

 

We have recently decided to standardise louver lengths for particular widths or styles of louvers we can supply, for example our 15mm wide standard louvers range in 10mm increments from 50mm through to 300mm lengths. Other Louver styles or widths range in lengths of 50mm etc.

Available Speedex Louvre Shapes & Sizes (currently being updated!! More louver styles and info coming soon!)

We have recently decided to standardise our louver lengths for particular styles or widths of louvers that we supply. For example our 15mm wide standard louvers will range from 50mm through to 300mm lengths in 10mm increments. Other louver styles will also have several common available lengths.

We manufacture a range of standard, stock and custom louver styles and sizes. 

Please note, we are tool makers and can make any custom louver length as this will require additional tooling and may incure additional costs if non-standard lengths available on the shelf. So we would like to offer a range of common lengths in different styles which should be able to satisfy most of our customer requirements with off the shelf tooling.

***PLEASE CHECK OR EMAIL US IF LOUVRE STYLE OR SIZE IS AVAILABLE- THANKYOU! - our online contact form currently has a broken link so please write to us directly from your email address to speedex@speedex.com.au so we recieve it!

 

Can panels have different louver lengths?

Yes, as long as a customer gives us a drawing or describes in an email or phone what they require we can supply louver panels with different louvers lengths on each panel

What are the widths of louvers available?

3mm wide

12mm wide

15mm wide

19mm wide &

25mm wide

More sizes to be added in future

 

What is the maximum length of individual louver or vent we can make?

Depending on the width of louver sizes we offer such as 12mm, 15mm, 19mm 25mm etc we currently offer maximum length of 400mm. But we have recently added a 515mm wide Kombi Van louver. So we are hoping to offer up to 500mm max wide individual louvers in possibly our 19mm high and 25mm high louver sizes , but due to stresses on our press we would have to discuss first with customers if your panel can be pressed or not. But 300mm to say 400mm lengths can done.  The shorter louvers require less tonnage than longer ones. But we are constantly experimenting and adding sizes due to customer requests.

Can Pitch between individual louvers be equal or different spacing?

As long as the spacing is equal or greater than the minimum pitch allowable for each style of louver, then yes any pitch is allowable within reason, usually try to go up in 1mm increment. If you require really precise spacing then we can lasercut panels to be any exact pitch to any decimal place.

But generally try to go up in 1mm increments in pitch so we can avoid lasercutting.

We can also make different spacing or gaps if specified. As long as you send us a drawing so we can follow.

Available Material and Thicknesses

Our louvers are available in aluminium, steel or stainless steel from 0.5mm to 1.5mm thick in Aluminium and say 1mm up to 2mm in steel. If specifiy mild steel we usually make in 1mm thick, but can make in thicker steel if required. Again it is harder to press in thicker steel so we try to aim for 1mm. We usually restrict stainless steel louver panels to 1mm or less as stainless steel is much more difficult to punch and press due to greater tensile strength etc.

Is there a minimum margin allowable around pressed louvers?

Yes we do have minimum margins allowable around a particular pressed louver and also between adjacent louvers side by side. This is due to the fact that if margin is too little the material or panel itself will distort, tear, bend or stretch. We also require a minimum margin "meat" to press the actually steel into shape.

SIDE MARGINS - please allow a minimum of approximately 25mm on either side of a particular louver and the outside perimeter of the panel. (We may be able to do less say 20mm but depends on tooling and panel type)

TOP and BOTTOM MARGINS - please allow a minimum of 20mm approximately on top and bottom margins

ADJACENT or SIDE BY SIDE MARGINS - Please allow a minimum of 25-20mm between louvers spaced side to side, or a minimum gap of 20mm.

This information above relates to our standrad or most common louvers style of 15mm wide, if louvers are wider such as 24mm or 30mm then margins may have to be increased to prevent material from stretching or tearing.

Can we press existing panels or bonnets?

Yes we now have associated tooling to be able to press existing bonnets or curved panels.  This example below is of a Porsche Louver Panel where we presed in several rows of louvers into an existing panel.

A second example of pressing louvers into an existing panel can be seen in picture below, which is off a Jaguar MK2 bonnet.

We pressed in 4 rows of 15mm wide x 150mm long louvers into the existing bonnet. Please note that the paint around the louvered area needs to be stripped to bare metal on both sides as the paint was very thick.

And sound dampening tar had to be removed from the underneath of the panel only in areas to be pressed.

But as you can see we can do existing car bonnets. So if you have an existing bonnet please write to us so we quote and organise doing for you.

As a general rule we require the bonnet to be dropped off at our premises and left with us for 1 - 2 weeks so we can fit in
