Gas retentive sheeting, hygiene curtains and quarantine covers, made In Brisbane

A fumigation sheet either holds gas for the full exposure period or the treatment fails. There’s no partial credit. It has to withstand being dragged over a stack and pulled off again, repeatedly, without splitting at the seams.

We manufacture fumigation sheeting, food area curtains and quarantine covers at our factory in Brisbane and supply operators across Australia. Tell us the material or the performance standard required and we’ll source it, certify it where certification is available, and make it to your dimensions.

Material specification and sourcing

Please note, we are a manufacturer, not a fabric mill and not a certifier. What we bring is specification judgement and supply access: knowing which construction suits the application, sourcing it from a supplier who can certify it, and manufacturing it correctly.

MATERIAL CLASSSPECIFIED FORTYPICAL SITE APPLICATION
Gas retentive coated fabricsLow permeability, selected on the gas being used and the exposure period required. Weldable, so seams are continuous rather than perforated. Tested material currently availableFumigation sheets for stacks, containers, commodity and under tarp treatment
Heavy duty reusable gradesHigher weight and abrasion resistance for sheets that are dragged, folded and redeployed repeatedly rather than used onceRepeat use fumigation sheeting, contract fumigation operations
Food contact certified materialsMaterials certified by the supplier as suitable for contact with food, supplied with that certificationProduct contact covers, chute and hopper covers, processing area screening
Reinforced PVC, washable gradesSmooth, non absorbent surface that stands up to a wash down regime and cleaning chemicalsHygiene curtains, processing area dividers, splash and washdown screening
Clear and tinted PVCVisibility retained while an area is separated for hygiene or temperatureProcessing area panels, viewing sections in dock and divider curtains
Thermal and insulated curtainsTemperature separation between zones without a fixed wallChiller and freezer dock curtains, cool room entries, temperature zoning
Mesh and ventilated fabricsAirflow retained while insects, birds or debris are excludedVentilated storage, insect and bird screening, drying and airing areas
Fire retardant gradesFlame retardant treatment or inherently FR construction, supplied with the manufacturer’s certificationPlant areas and enclosures where the specification calls for it


What determines your fumigation sheet specification

  • The gas and the exposure period. Gas retention is the whole point of the sheet. Tell us what you are using and how long the treatment runs, because that drives the material class before anything else does.
  • Single use or repeat use. A sheet that will be dragged over a stack and redeployed fifty times is specified for abrasion and seam strength, not only for permeability. That is a different fabric and a different weight from a sheet used once.
  • The size and shape of what you are covering. Stack dimensions, container size, and how much ground seal you need all change the finished sheet size. We make to the stack rather than supplying a nominal size and hoping it reaches.
  • How it is sealed to the ground. Sand snakes, weights or a welded ground sheet each change the hem and edge construction we build in.
  • Seam method. A welded seam is continuous. A stitched seam has a needle hole every few millimetres, which on a gas retentive sheet is a leak path. This is why fumigation sheeting is welded wherever the fabric allows it.
  • Repair expectations. Fumigation sheets get punctured. Ask about patch kits and repair turnaround when you order rather than when it happens.

What we fabricate

Fumigation sheets and tarps

Gas retentive sheeting made to your stack, container or commodity dimensions, welded rather than stitched wherever the fabric allows, with the hem and edge construction to suit how you seal to the ground.

Quarantine and biosecurity covers

Covers and sheeting for quarantine holding, inspection and treatment areas, made to the area and to whatever the job requires.

Food processing area curtains and screens

Hygiene curtains, processing area dividers, splash screens and washdown screening in smooth, non absorbent materials that stand up to a cleaning regime.

Chiller, freezer and dock curtains

Temperature separation curtains for cool room entries, chiller docks and temperature zoned areas, made to the opening and to the traffic going through it.

Commodity, grain and bulk storage covers

Covers for stored commodity, bunkers and bulk storage, made to the pile or the structure.

Insect, bird and ventilation screening

Mesh screening where airflow has to be kept while pests are excluded.

Machinery, hopper and chute covers

Covers cut to the equipment, including in product contact areas where a certified material is required.

Repairs, patching and re-hemming

Fumigation sheets and hygiene curtains both take damage in normal use. We patch, reweld, re-hem and replace fittings, including on sheets we did not make. On a reusable sheet, a repair is almost always the cheaper path.

Working with us

  • Manufacturing: Everything is made at our Redland Bay factory. Cutting, welding, stitching and hardware all happen under one roof, so a variation or a second sheet is a short turnaround rather than a re-order.
  • Material certification: Tell us the material or the performance requirement the job calls for and we will source material the supplier can certify, and pass that certification through with the goods. If your documentation needs it supplied with the quote, say so and it will be.
  • Site measure: When possible, we attend site to measure and consult. For work further out we can work from drawings or measurements taken by your team to a template we supply.

We needed a small repair to a swag and LJ Covers was able to fix it on the spot. They were efficient, professional and very easy to deal with. I would have no hesitation in recommending them to anyone needing repairs or canvas work.

Called in to see them about a little modification on a caravan annex piece and was greeted with very friendly and helpful staff who understood my needs. I dropped the piece off in the morning and I had a call back later that morning to say it was ready. Service 5/5 Quality of work 5/5 Value for money 6/5 Definitely recommend this company for all your requirements 👍

Our business recently got LJ Covers to make a large industrial strength 15m x 10m 16oz canvas ripstop tarp and couldn’t be happier. It’s heavy-duty, strong, and the tie-downs are solid. The fabric quality is much better than tarpaulins we’ve bought elsewhere before. Service was great the whole way through. We also saw they do trailer canopies, so got one organised as well, and that turned out spot on. Heavy-duty PVC, zips and all the bells n whistles. Very happy and would definitely recommend LJ Covers

This company is incredible. The workers there are friendly and helpful, they provide good quality products. The materials and effort they put into each customer is 5/5. I had them do my shade sails and it looks amazing, the fabric was and felt really durable to hold against the storms and high wind where I live. I Highly recommend going to LJ covers!

Fumigation and food FAQs

Got a question? Find answers to common questions about our services, products and custom solutions.

Bigger than the stack. Give us the stack or container dimensions and how you seal to the ground — sand snakes, weights or a welded ground sheet all need different edge allowance. We make to the stack rather than supplying a nominal size and hoping it reaches.

Welded wherever the fabric allows it. A welded seam is continuous. A stitched seam puts a needle hole every few millimetres, which on a gas retentive sheet is a leak path.

That depends on the grade, how it is handled and how it is stored. A heavier reusable grade is specified for abrasion and seam strength rather than permeability alone. Tell us how many cycles you expect to get and we will tell you honestly whether the grade we are quoting will do it.

Yes, and on a reusable sheet it is almost always the cheaper path. We patch, reweld and re-hem, including on sheets we did not manufacture.

Yes. We source material the supplier can certify and pass that certification through with the goods.

Yes. Smooth, non absorbent materials suited to cleaning are a normal specification for us. Tell us what chemicals are used and how often, because it changes the recommendation.

Yes, made to the opening and to the traffic going through it.

The dimensions, what the sheet or curtain has to do, the gas and exposure period if it is fumigation work, how it is sealed or fixed, any material certification required, and when you need it.
