Rubber Sheeting/Natural rubber
Natural Rubber Sheet
Abrasion-resistant natural rubber sheet in 38, 40 and 60 Shore, red or black. Our most widely supplied sheet for slurry pipes, tanks, chutes and general industrial use.
AU Industries mixes natural rubber compounds and mills them into sheet on our own calenders in Boksburg, Gauteng. Natural rubber is the standard choice for wet abrasion: it is resilient, so fine particles bounce off rather than cut, and it has the tensile strength and elongation to take impact without tearing.
We make two main hardnesses. 40 Shore is soft and resilient for fine slurry abrasion in pipes, cyclone feeds, pump casings and tank floors. 60 Shore is harder and resists the gouging and cutting of coarse, impact-loaded material in chutes, hoppers and screen decks. A softer 38 Shore grade and our application-specific Tigeye and SlurryShield grades are made for slurry duty too.
Black 40 Shore and red 40 Shore are held in stock in standard widths, so standard orders turn around quickly.
Best for: Slurry abrasion, impact wear and general industrial rubber sheet. Not sure which sheet you need? See our full rubber sheeting range or tell us the duty and we will specify the grade and gauge.

Applications
- ▪Slurry pipelines, spools and bends
- ▪Tank and vessel linings
- ▪Chutes, hoppers and launders
- ▪Cyclones and hydrocyclones
- ▪Pulleys and pump linings
- ▪Screen decks and wear pads
- ▪Gaskets, skirting and wear strips
Not recommended for
Oils, acids, hydrocarbon solvents and strong oxidising agents. Use nitrile for oil and bromobutyl for acid service.
Thickness guide
| Thickness | Typical use |
|---|---|
| 3mm – 5mm (thin rubber sheet) | Gaskets, wear pads, skirting, light abrasion and lining where weight or clearance matters |
| 6mm | The usual lining gauge for general slurry abrasion in pipes, tanks and cyclones |
| 10mm – 12mm | Pipe bends, reducers and chute impact points where the flow changes direction |
| 15mm – 25mm (heavy rubber sheet) | Heavy impact and wear zones: chutes, hoppers, transfer points and screen decks |
How to order
1
Tell us the duty
Compound or duty, thickness, width and how many rolls. A drawing or the item being lined helps.
2
Get a quote
We quote per compound, thickness and quantity, by the roll or as part rolls and custom widths for smaller jobs.
3
Collect or delivery
Collect from Anderbolt, Boksburg, or delivery across Gauteng, weekly routes into Mpumalanga and freight across Southern Africa.
Every roll leaves the mill labelled with the compound, hardness, thickness and production date for batch traceability. Need the equipment lined too? We do rubber lining in our workshop or on site.

AU 40 Shore Black Natural Rubber Compound
AU 40 shore black natural rubber is our most widely supplied compound — a classic 40-durometer natural rubber tuned for abrasion resistance in mining slurry duty. Used across our lining, sheeting, and fabricated rubber product lines.
Questions
What is the difference between 40 Shore and 60 Shore natural rubber sheet?+
40 Shore is softer and handles fine-particle slurry abrasion in pipes, tanks and cyclones by absorbing the wear through its resilience. 60 Shore is harder and resists the cutting and gouging of larger, sharper particles in chutes, hoppers and screen decks.
Is red or black natural rubber sheet better?+
The colour is a compound choice, not a quality grade. Our red 40 Shore compound has the lower abrasion loss on its data sheet (95 mm³ max against 150 mm³ for black 40 Shore). Black 40 Shore is the most widely used general-purpose grade. Compare the data sheets on this page or ask us which suits your duty.
What thicknesses of natural rubber sheet do you make?+
From 3mm to 25mm as standard, so thin rubber sheet at 3mm to 5mm and heavy sheet at 20mm to 25mm come off the same mill. Gauges outside that range are milled to order.
Is the sheet supplied steam-cured or pre-cured?+
Either. Steam-cured (uncured) sheet is for items that are lined and then vulcanised in an autoclave, which gives the strongest bond. Pre-cured sheet is already vulcanised, for lining that cannot go through an autoclave, such as large tanks and on-site work. Tell us how the sheet will be applied and we supply the right cure state.
Can I buy this rubber sheet per metre?+
We sell rubber sheeting by the roll (standard 1200mm × 12m, up to 12.5m long on request), plus part rolls and custom widths for smaller jobs. We do not sell off the roll per metre. Send us the compound, thickness and quantity you need and we will quote.
Where can I collect or get rubber sheet delivered?+
Collect from our Anderbolt, Boksburg facility on the East Rand, or we deliver across Gauteng and on our weekly routes into Mpumalanga, with freight to the rest of South Africa and to Mozambique, Namibia, Zambia, Botswana and Zimbabwe.
