Vinyl Coated Schedule 40 Pipe – Heavy-Duty Round Fence Posts (Black, Brown & Green)
- Full-weight Schedule 40 steel pipe — heavy-wall construction for demanding fence and gate applications.
- Heavy PVC coating (10+ mil) — provides durable corrosion protection and a clean, finished appearance.
- ASTM F1083 steel core — underlying pipe meets ASTM F1083 requirements for fence framework.
- Specification-compliant coating — meets ASTM F1043 Group I-A, RR-F-191, and AASHTO M-181.
- Available in Black, Brown & Green — designed to match vinyl-coated chain link systems.
Vinyl coated Schedule 40 pipe combines the structural strength of full-weight Schedule 40 steel with a bonded heavy PVC coating engineered for outdoor fencing environments. It is commonly specified for commercial, industrial, and public-space installations where corrosion resistance, appearance, and long-term durability are critical.
This product is supplied directly through our vendor network. The underlying steel pipe meets ASTM F1083, while the PVC coating system complies with widely referenced fence and transportation specifications. Domestic (Made in USA) material may be available by request for projects that require U.S. manufacturing.
Most Common Uses
- Vinyl coated chain link fence posts — line posts, terminal posts, corners, and ends.
- Gate posts — added strength for swing gates and high-cycle openings.
- Top rail & brace rail — cohesive framework for vinyl-coated fence systems.
- Parks, schools & public facilities — clean appearance with long-term durability.
- Coastal or corrosive environments — PVC coating adds protection beyond galvanization alone.
Why Choose This
- Structural strength — true Schedule 40 wall thickness for demanding installations.
- Heavy PVC coating — 10+ mil coating helps resist abrasion, moisture, and UV exposure.
- Specification-ready — commonly referenced in commercial, municipal, and DOT-influenced projects.
- OD-matched compatibility — works with standard chain link fittings sized by outside diameter.

Schedule 40 vs. SF40 (SPS-40)
Schedule 40 and SF40 (also called SPS-40) are not the same product and should not be substituted unless the project specification explicitly allows it.
- Schedule 40 — full-weight pipe defined by schedule-based wall thickness and weight per foot, commonly referenced under ASTM F1083.
- SF40 / SPS-40 — high-strength framework categories that typically use higher-yield steel with thinner walls and reduced weight, often tied to ASTM F1043 classifications instead of schedule wall tables.
If your plans or submittals require Schedule 40 or ASTM F1083, this product meets those requirements.

Comparison
- Vinyl coated vs. galvanized Schedule 40 — PVC coating provides color matching and additional surface protection.
- Schedule 40 vs. SF40 — Schedule 40 is full-weight pipe; SF40/SPS-40 is a high-strength alternative requiring spec approval.
- PVC-coated Schedule 40 vs. light-wall coated pipe — Schedule 40 offers greater rigidity and long-term alignment.
