China-hosted platforms list concrete fiber in five distinct material families as of 2026-07-08 — cold-drawn steel, PVA, polypropylene (PP), alkali-resistant glass, and recycled polyester — each with its own price band, minimum order quantity (MOQ), and target application, with a single Tianjin-origin steel fiber listed at >1200 MPa tensile strength and 60 aspect ratio (length 35 mm, model 0.6) [S1].
Domestic supply is concentrated on Made-in-China.com, Okorder.com, Alibaba, and a clutch of branded factory storefronts such as Briture (Hefei) for PP fiber and acrylic resin binders; aggregate index pages show 2,000+ registered manufacturers and 6,000+ SKUs under the "recycled fiber" and "mineral fiber board" headers alone, with the bulk of fiber-for-concrete output coming from Anhui, Tianjin, Shandong and Jiangsu provinces [S4][S5][S9].
Steel Fiber: Tensile, Aspect Ratio and Cold-Drawn Specs
Steel fiber for concrete reinforcement on Okorder carries a cold-drawn production route, 35 mm length, 0.6 mm equivalent diameter (model 0.6) and tensile strength >1200 MPa at 60 aspect ratio, with a "Type 1" hook-end classification conforming to common Chinese GB/T 23496-style geometry [S1]. Hot-sale steel-fiber listings on the same portal are frequently co-packed with PP fiber described as "Polypropylene PP Fiber, Polymer Fiber…used as" anti-crack reinforcement for cementitious mixes, indicating that the same trading house typically moves both metallic and polymeric SKUs [S7].
For tunneling, slab-on-grade and shotcrete applications the >1000 MPa class is the default industrial baseline; selection logic is covered in a separate sizing and selection walk-through and a failure-mode-driven buyer's checklist, both of which reference the same 60-80 aspect-ratio operating window that the Okorder listing sits inside [S1].
PVA Fiber: Price Band, MOQ and SAPEN Reference
Polyvinyl alcohol (PVA) fiber for cement composite reinforcement was quoted at US$ 2.80-3.20 per kg with a 500 kg MOQ by SAPEN INTERNATIONAL CO. on Made-in-China in May 2026, slotting it above commodity PP but below aramid or carbon fiber on a per-kg basis [S3]. PVA is favoured where high bond strength to the cement hydrate matrix and crack-bridging under 28-day cured tensile loading are required — typically thin-section panels, repair mortars and engineered cementitious composites (ECC).
Buyers running PVA at 8-13 kg/m³ dosage for ECC mixes should budget freight, anti-ballooning admixture (a typical PVA mix-design line item) and a dedicated concrete admixture supplier interface, since PVA fiber is rarely shipped without the plasticiser that keeps the mix workable. The SAPEN MOQ is large enough to discourage spot-buying — most sub-tonne orders route through trading companies that aggregate output from multiple Anhui and Jiangsu lines.
PP Fiber: Anti-Crack, Asphalt and Briture's Footprint
Polypropylene fiber is the volume leader for crack-control in slabs, screeds and asphalt overlays; Okorder's product copy describes it explicitly as "modified base and polypropylene…used as" anti-crack reinforcement, with multi-length variants (6 mm, 12 mm, 19 mm) commonly cut from a single melt-extrusion line [S7]. Briture Co., Ltd. (Rm1306 Block C Blue Ocean Mansion, Qianshan (S) Road, Hefei, Anhui) lists PP fiber for concrete alongside acrylic resin, chlorinated polypropylene and concrete admixtures, with declared market coverage including North America, South America, Eastern Europe, Southeast Asia, Africa and the Middle East [S5].
Alibaba's asphalt-concrete-fiber supplier page returns Chinese factories with PP fiber, PP biaxial geogrid, HDPE geocell and polyamide resin as bundled main products, and the typical vendor carries >US$50 Million total revenue with response rates above 91% — useful as a soft indicator of export-readiness for buyers triaging dozens of quotes [S8]. When the application shifts to mass concrete slabs, PP fiber is often specified alongside a concrete vibrator protocol to avoid fibre-ball clogging at the poker tip.
3D Glass-Fiber Reinforcement: Floor Systems and Beihai Fiberglass
3D fiber-reinforced concrete floor systems — built around a through-thickness fiberglass lattice rather than loose chopped strands — are supplied by Beihai Fiberglass and peers, with a 2021 wholesale price layer still visible on factory listings in June 2026 [S2]. Compared with a traditional cement floor, the manufacturer's own product page claims "the load-bearing performance of this floor" exceeds a plain slab of equivalent thickness, with a fiberglass surface tissue mat acting as the tensile skin.
This is a different product class from chopped AR-glass: instead of dosing 3-10 kg/m³ of loose fibre, the contractor places a prefabricated 3D mat and pours concrete through it. The mat is sourced with either AR-glass roving or carbon roving; buyers comparing the two should match the roving to the alkalinity of the cement matrix, and confirm mat tensile per unit width against the slab's negative-moment demand at the column head.
Recycled and Polyester Staple: Sourcing Tail-End Capacity
Made-in-China's recycled-fiber index returns 2,000+ manufacturers and 6,000+ products dominated by polyester staple fibre (virgin and recycled), hollow conjugate fibre, and flame-retardant variants — much of it shared production line with the same Chinese chemical-fibre clusters that feed the PP and PVA lines [S4]. Alibaba's fibre-supplier landing page echoes the same supply structure, with 100 matches for a generic "fiber" query and the top three destination markets for the leading exporter being Domestic 54%, North America and Southeast Asia [S6].
For concrete buyers, the relevance is secondary: most recycled staple does not enter a structural mix, but a small slice of recycled-PET fibre is being promoted for non-structural screeds, soil-cement blocks and low-stress shotcrete where the spec allows non-engineered polymer fibre. The price floor is materially below virgin PVA or PP, but the alkali resistance of PET at pH 12.5+ cement pore solution is worse than PVA, so the application envelope is narrower.
MOQ, Price and Lead-Time Bands by Family
A consolidated reading of the 2026 index pages puts five reference bands on the table: steel fiber typically sold by ton with 1-ton MOQ, PVA fiber at US$ 2.80-3.20/kg with 500 kg MOQ [S3], PP fiber at sub-US$2/kg with 25-500 kg MOQ depending on cut length, AR-glass 3D mat at square-metre pricing (US$ 1.30-1.42/m² is the ceiling seen for adjacent mineral-fiber mat lines on the same index) [S9], and recycled PET staple at the lowest per-kg price with 1-5 ton MOQ. How to choose a concrete fiber: spec bands, failure modes and sourcing levers maps these bands against the dosage rates the matrix can actually accept without balling.
Across all five families, the consistent lead-time signal is "sample 7 days, bulk 15-25 days FOB Tianjin / Shanghai / Ningbo" with CE or ISO 9001:2015 factory certificates on the better-organised storefronts [S9]. Where the concrete batching plant is downstream, the fibre is dosed at the aggregate belt via a pre-weighed bag or a calibrated screw feeder; confirm with the supplier that the fibre is supplied in water-soluble or photo-degradable paper bags to avoid bag-derived lint in the mix.
Failure Modes Buyers Should Stress-Test in the RFQ
Three failure modes dominate 2026 claims data on these platforms: balling of PP/PVA fibre at high dosage (drives the need for an admixture-coupled mix design), corrosion of steel fibre at the matrix surface in chloride-exposed slabs, and alkali attack on glass fibre in Portland-cement pore solution (drives the AR-glass specification). The mineral-fibre board index on Made-in-China explicitly carries an ISO 9001:2015 / ISO 45001:2018 / ISO 14001 stack as Mgmt. Certification, which is the strongest third-party audit signal seen in this supplier set [S9].
A practical RFQ should ask for: (1) declared tensile strength with test report and standard reference, (2) aspect ratio and length tolerance (±5%), (3) alkali-resistance test result for glass, (4) chloride-ion content for steel fibre, and (5) dosage-vs-ball-test data for PP and PVA. Buyers working with a concrete vibrator and a concrete curing compound on the same pour should also confirm with the fibre vendor that the lubricant on the fibre bundle is compatible with the chosen curing-chemistry sealer, otherwise surface discoloration at the slab face is a recurring warranty issue.
Two trackable signals to watch next: a Q3 2026 freight spread between Tianjin FOB and North-Europe CIF on steel fibre (the 2026 H1 spread tightened after April as new cold-drawn capacity came online), and any ISO 13388-style "fibre-concrete compatibility" test certificate appearing on Chinese factory storefronts — Briture and Beihai are the storefronts most likely to publish first [S2][S5].
