Waterproof Shade Net 100% 400GSM Green – 25m x 3m Roll (75 m²) | Shabbiri Hardware Kenya
Blocks 100% of sun and 100% of rain — in one 25 m run
A fully waterproof, UV-stabilised HDPE shade sheet supplied as a ready-to-fix 25 m × 3 m roll (75 m²) in green, with reinforced double-stitched hems and rust-free eyelets. Ideal for car parks, carports, walkways, patios, greenhouses, livestock shelters and site covers.
Why 400 GSM matters in Kenyan weather
A sealed sheet, not a mesh
Standard 70% or 90% shade nets are knitted with gaps — they cool a space but rain goes straight through. This is a closed, laminated HDPE sheet coated on both faces: the shading of a shade net with the sealing of a tarpaulin.
Heavy-duty class
400 GSM is the weight used for permanent car park canopies, market roofs and long walkways — higher tear resistance, better wind stability, longer life under strong UV.
One continuous 25 m run
No joins along its span, 3 m wide. Covers five to six car bays in a line, a 25 m walkway, a long greenhouse section or a boundary rain screen — with no seam sealing mid-run.

Buying tip: GSM is the most useful number when comparing waterproof shade nets. If a supplier only says “heavy duty”, ask for the weight per m². A 75 m² roll at 400 GSM should weigh close to 30 kg — weighing the roll is the quickest honest check.
Where this waterproof shade net is used
🚗Car parks & carports
A 25 m run shelters 5–6 bays end to end, keeping vehicles cool, dry and paintwork protected.
🚶Walkways & corridors
Covered access for schools, churches, clinics and offices — one roll gives 25 m of cover.
🏡Patios & verandas
Turns an open terrace into an all-weather outdoor room. Rain runs off, furniture stays dry.
🌱Nurseries & drying sheds
Full block-out roofing for propagation areas, drying sheds and seedling stores.
🐄Livestock & poultry
Rainproof roofing and windbreak side-curtains for sheds, pens, poultry runs and calf housing.
🏗️Construction sites
Scaffold screening, cement and aggregate covers, concrete curing and site store roofing.
🛒Market stalls & kiosks
Durable roofing for open-air markets and food courts through dry and wet seasons.
🧱Privacy & boundary screens
Fixed to a fence or wall it becomes a solid screen that also stops wind-driven rain and dust.
⛺Events & tents
Emergency rain covers for tents, stages, sound equipment and catering areas.
Fix it right in 10 steps
Most shade net failures are installation problems — follow these and the sheet lasts for years.
Plan & prepare
Measure and plan the slope
Set fixing points so the sheet falls at least 1 in 20 across the 3 m width — a minimum 150 mm drop.
A flat fix ponds water — just 20 mm over 75 m² is over a tonne of loadAllow slack for tensioning
Set anchor points 150 – 250 mm beyond the sheet edges so ropes and turnbuckles have room to pull.
Never plan for the sheet to reach edge to edge with no rope runPrepare the frame
Fix eye bolts, hook bolts or purlin clamps at about 1 m centres. Tape over sharp edges, bolt threads and weld beads.
Abrasion, not sunlight, is what kills most shade netsLift & fix
Unroll on a calm morning
Unroll the 25 m length on clean ground, check for transit damage, then lift into place.
Use 2 – 4 people: a 30 kg sheet catching wind at height is dangerous aloneFix the four corners first
Rope through the reinforced corner patches and tie loosely. Square the sheet before tightening.
A sheet fixed out of square will always crease and flapWork from the centre outwards
Fix the middle eyelet of each edge, then work towards the corners, alternating left and right.
Spreads tension evenly and stops diagonal wrinklesTension, seal & settle
Tension evenly — firm, not drum tight
Taut with no sag pockets, but not stretched until eyelets deform.
An eyelet pulling into a teardrop means release and redistributeSeal the joins
Lap the upper sheet over the lower by 150 – 200 mm in the direction of fall.
Seal with PE-compatible seam tape or bituminous lap tapeProtect the eyelets
Keep eyelets on the high side of the slope and cushion the pull with a rubber washer or bungee.
Avoid hard steel-to-metal contact at the eyeletRe-tension after two weeks
Polyethylene relaxes slightly after first loading. Go round every rope once.
Then re-check at the start of every rainy seasonKeep it working season after season
🧽 Cleaning
Plain water and a soft brush, or mild soap. Never thinner, petrol, diesel, acetone or a wire brush — solvents attack the lamination.
🔍 Inspection
Check eyelets, corners and seams each rainy season. Patch small tears on both faces with PE repair tape — a 20 mm tear can become 2 m in one windy night.
📦 Storage
Only store when fully dry. Fold loosely, keep in shade, off the ground and away from rodents.
✂️ Cutting to size
Use a sharp or hot knife, fold the edge back 40 – 50 mm, double stitch, and fit new eyelets before tensioning.

Frequently asked questions
Is the 400GSM green shade net really 100% waterproof?
Yes. Unlike an open-weave 70% or 90% shade net, this fabric is laminated and coated so no water passes through the sheet body. The only possible entry points are stitched seams and eyelet holes, which is why the installation guide places them on the high side of the slope.
How many square metres does a 25m x 3m roll cover?
75 m² — roughly five to six car bays in a line, a 25 m covered walkway, a long greenhouse roof section, or a 25 m boundary screen.
How long will it last in the Kenyan sun?
Three to five years outdoors with correct tensioning. The UV stabiliser is compounded into the yarn, so it doesn't wash off. What shortens life is flapping, ponded water and abrasion on sharp frame edges — all installation issues.
What slope should I give the net so water drains?
A minimum fall of 1 in 20 — about 5%, or a 150 mm drop across the 3 m width. Anything flatter holds water, forms a pond and eventually tears the eyelets out.
Can I cut the roll to a smaller size?
Yes. Cut with a sharp or hot knife, fold the edge back 40 – 50 mm, double stitch it and fit new eyelets. A raw edge left unfinished will fray and tear in wind.
Does it come in colours other than green?
Green is stocked as standard. Green/silver and green/black, plus sizes such as 50 m × 3 m and 50 m × 4 m, are available on order. Call 0741 042484 to check stock.
Can it be used as a greenhouse cover for growing plants?
Only where full block-out is wanted — drying sheds, curing rooms, stores or hardening-off areas. It stops 100% of light, so it is not suitable over growing crops. For those, use our 70% or 90% knitted shade nets.
