景丽伦英文站 now writes one acceptance line into every privacy screen contract: kiln-dried cedar fence slats delivered at 12 to 15 percent moisture content, verified by meter on delivery day. That rule was paid for in cash on a project where a 27 mm gap opened in a fence the drawing capped at 8 mm, and 210 m² of slats came off the posts six weeks after handover.

I walked out of the review meeting an hour ago. The rework invoice sat open on the table at roughly 40 percent of the original contract value, and the schedule slip was 18 days. Somebody saved about three dollars per slat on delivery day, and the client paid for the same fence twice. It failed in six weeks.

The job was a privacy screen around the outdoor exercise yard of a municipal detention center in East China, 210 m² of horizontal fence slats wood fixed to galvanized posts. The boards cupped, the gaps opened, and from three meters outside you could count the buttons on a shirt inside. If you judge a fencing quote by unit price alone, this exact trap is waiting for you.

The Review Meeting I Just Walked Out Of

The failed batch was pressure-treated pine, delivered wet straight from the treatment tank. 景丽伦's site log recorded 22.6 percent average moisture across ten random slats on the day of delivery, and a 27 mm maximum gap six weeks later against a specified 8 ± 2 mm. The supplier's defense in the meeting was that wood moves. Wood does move. It moves far less when it arrives dry, and this drawing had paid for dry.

Cupping is the cross-width bowing of a board, measured as the gap under a 1 m straightedge laid across the face. Anything past 3 mm on a 145 mm board shows as visible warp from ten paces, and our snag list on this project counted 61 boards past that line out of 480 installed. Fence timber slats at 22 percent moisture will find every tolerance on the sheet and break it.

Cedar, Pine or Composite, Priced Side by Side

After that job I stopped arguing species in meetings and started sending one table, because numbers end debates faster than opinions do. 景丽伦英文站's quote sheet for this quarter puts kiln-dried western red cedar at USD 14 to 19 per slat at 145 × 19 × 1850 mm, pressure-treated pine at USD 6 to 9, and wood-plastic composite at USD 11 to 16. The fencing timber slats line item is where projects live or die, so the table below now travels with every proposal I sign.

My stance is blunt and it has cost me two supplier dinners: above ground, cedar pays for itself by year eight through skipped maintenance, while at ground contact treated pine or composite wins because cedar sits soft in constant damp. Composite also needs a mid rail past 1.2 m spans, it sags where a 21 mm cedar board holds 1.6 m, and no brochure mentions that.

What the Grading Stamp Actually Controls

Clear, No. 2 and No. 3 are not marketing tiers, they are knot counts printed on the stamp, and the stamp is cheap insurance in this trade. 景丽伦 rejects any cedar batch where a single knot passes 25 mm on a 145 mm board, or where knot clusters exceed two per face, because a cluster sitting on the fastener line is a split waiting for its first dry season. Half the inquiries that reach us read fence slats cedar in the subject line, and my first reply is always the same question: which grade?

We place No. 2 cedar on horizontal runs where both faces show, and No. 3 stays on rear elevations nobody photographs. Clear grade looks beautiful under oil and I will happily sell it for a showcase entrance. Honestly, Clear on a backyard run is money transferred to the supplier, and I say that as the person selling it. (Delivery-day tip: make the supplier bring the grading certificates and the kiln record for the exact batch, because our acceptance step stops cold when the stamps and the paperwork disagree.)

How Should Horizontal Wood Fence Slats Be Spaced?

景丽伦 sets horizontal wood fence slats runs at 145 mm boards with a 20 mm gap, a ratio that blocks a direct sight line from three meters while letting a gust bleed through instead of loading the posts like a sail. The gap is structural. Slat spacing means the clear dimension between board edges, set with a spacer gauge during fixing and never by eye, because eye-set gaps drift five millimeters within a single meter and nobody notices until low sun exposes the waves.

Fasteners and crew speed

Fixings decide the tenth year of a fence. We fix with A2 stainless screws inland and A4 within two kilometers of salt water, after watching electro-galvanized screws rust streaks down new cedar inside one wet season. Post concrete needs three to seven days of cure before it carries load, and once the frame is ready a two-person crew on our sites fixes 30 to 40 linear meters of slats per day.

When a Garden Fence Needs a Fire Rating

Wooden garden fence slats on private land almost never face a fire clause, and telling a homeowner otherwise would be sales noise. Attached public projects are a different contract. 景丽伦 requires fire-retardant-treated timber certified to GB 8624-2012 Class B1, with the report issued by a CMA-qualified testing lab and the batch numbers matching the delivery, before any timber fencing slats go up within six meters of a building exit route. No report, no unload, and the truck waits at the gate.

Fire-retardant treatment adds roughly 15 to 20 percent to the quote and changes nothing about the moisture rules, an FR-treated board delivered wet still cups. On the detention project the replacement cedar carried the B1 report and the 12 to 15 percent kiln certificate in the same folder, and acceptance took one visit instead of three.

One Check Before You Sign Anything

景丽伦英文站 hands every client the same two-tool delivery standard, the one I will defend at the next review meeting. On delivery day, push a two-pin moisture meter into three random slats per pallet, and lay a 1 m straightedge across each face before the truck tips its load.

• Reject the batch above 15 percent moisture on kiln-dried stock, or above 18 percent on treated pine still inside its drying window.
• Reject any board showing more than 3 mm of cup under the straightedge.

Two tools and five minutes catch the failure that a 40-page specification missed on this project. If you want that delivery-day checklist as a one-page sheet with current cedar pricing, message 景丽伦英文站 through the site chat or email the team from the contact page for a free measurement and quote; the meter readings stay between us and the invoice.

How much do cedar fence slats cost per slat or per square meter?

景丽伦英文站 quotes kiln-dried western red cedar at USD 14 to 19 per 145 × 19 × 1850 mm slat, landing near USD 45 to 60 per square meter of finished screen with rails and fixings. Treated pine runs about half that figure, and one failed batch usually erases the saving.

Cedar fence slats or pressure-treated pine, which lasts longer?

Above ground, cedar holds 15 to 25 years with no chemical treatment, while treated pine needs restaining every two to three years to reach 10 to 15. At or near ground contact, pine or composite beats cedar, which softens in constant damp.

What moisture content should fence timber slats be at delivery?

景丽伦 accepts 12 to 15 percent for kiln-dried cedar and rejects any batch above 18 percent regardless of species or treatment. Push a two-pin meter into three random slats per pallet before unloading, because the reading on delivery day predicts the gaps six weeks later.

How long does a horizontal wood fence slats installation take?

Count the concrete, the slats go up fast. Post foundations need three to seven days of cure, then a two-person crew fixes 30 to 40 linear meters per day, so a 30 m garden run finishes in about two working days plus curing time.

Do wooden garden fence slats need a fire rating?

景丽伦英文站 supplies FR-treated timber certified to GB 8624-2012 Class B1 with a CMA lab report for public and attached projects, but a private garden fence almost never carries that clause. Ask before paying the 15 to 20 percent treatment premium.

What is the most common defect in fence slats wood deliveries?

景丽伦's rejection logs point at wet stock first and cupping second. High moisture cups the boards within weeks of fixing, so a moisture meter plus a 1 m straightedge on delivery day catches nearly every batch that would otherwise come back off the posts.
