China Aluminum Windows Accessories Suppliers Roundup

Today's digest covers six verified Chinese manufacturers across all four priority categories: sliding window rollers, corner keys/angle connectors, EPDM rubber seal strips, and aluminum profile assemblies. Supplier highlights range from Foshan's dominant roller factories to a Tianjin rubber specialist and two contrasting Foshan profile extruders.

Sliding window rollers and pulleys

Foshan Hanzson Building Materials Co., Ltd.

Location: Nanhai District, Foshan, Guangdong Platform: Diamond Member since 2026, Audited Supplier, Made-in-China.com B2B: hanzson.en.made-in-china.com

Founded in 2017 (with parent lineage tracing to Foshan Shunde Kangdian Metal Products Co., Ltd. est. 1998), Hanzson focuses exclusively on sliding window and door rollers. The company exports more than 60 million aluminium sliding rollers per year to around 50 countries, with active penetration in Southeast Asia, Oceania, and Europe.1

Product breadth covers stainless steel, aluminum alloy, and plastic casing roller types across residential, commercial, and industrial sliding applications — including anti-derailment silent rollers and heavy-duty airport gate wheels.

Key product lines on MIC include 2:

Product	FOB Price	MOQ
OEM stainless steel sliding window/door roller	$1.00–4.00/pc	300 pcs
Stainless steel silent roller (residential)	$2.00–3.00/pc	3,000 pcs
Plastic casing sliding double roller	$1.00–1.60/pc	3,000 pcs
Aluminum alloy double-wheel roller	$2.20–2.80/pc	3,000 pcs
Anti-derailment silent horizontal-sliding roller	$1.60–4.20/pc	3,000 pcs
U-groove 4-wheel pulley	$3.20–3.80/pc	3,000 pcs

Certifications are not publicly listed on the MIC profile. The low 300-piece MOQ entry point on the OEM stainless product makes Hanzson accessible for project-volume sourcing without committing to full-factory runs.

Guangdong 3H INC.

Location: Foshan, Guangdong Platform: Made-in-China.com; own website: 3hhardware.com B2B: 3h-hardware.en.made-in-china.com

One of South China's oldest window hardware manufacturers, 3H INC. was established in 1981 and has grown into a full-range accessories group covering rollers, handles, hinges, locks, friction stays, and EPDM sealing strips.3 Products are exported to more than 60 countries across Southeast Asia, South Asia, Africa, South America, Europe, and Oceania.

Certifications include ISO 9001:2015, ISO 14001:2015, OHSAS 18001, CE (rollers, sliding locks, handles, hinges, flush bolts, friction stays), UL, TÜV, CNAS laboratory accreditation, and AEO customs certification — a strong compliance stack for buyers specifying European or North American markets.

Roller line highlights:

PLD01B-PS — Zinc alloy single roller for sliding windows
PLTS02-AS — Carbon steel + double nylon roller
LTS834 — Aluminum sliding roller
JTSM07 — Middle roller for casement/sliding systems
Door/window roller claimed durability: 100,000 open/close cycles

Pricing is not published on the website; MOQ and pricing require direct inquiry. 3H also carries EPDM sealing strips (model 3H-Q01), making it a candidate single-source supplier for buyers needing both rollers and seals.

Corner keys and angle connectors

Ningbo Shineright Int'l Trading Co., Ltd.

Location: Ningbo, Zhejiang Platform: Diamond Member since 2016, Audited Supplier, Made-in-China.com B2B: hardwareasian.en.made-in-china.com

Established in 2008 in Ningbo's hardware belt, Shineright supplies door/window handles, latches, hinges, rollers, and corner keys — principally targeting the Africa, Middle East, and Europe markets. The company is a Diamond member and Audited Supplier on MIC since 2016 and operates an in-house aluminum profile processing area with ejection machines.4

Corner key / angle connector pricing from the product catalog:

Product	FOB Price	MOQ
Door & Window Roller (global market, zinc)	$0.30–0.50/pc	5,000 pcs
Steel roller for aluminum door & window	$0.10–1.00/pc	5,000 pcs
European-standard door & window roller	$0.10–1.00/pc	5,000 pcs
Corner/hinge (HL6503 sand-blast finish)	inquiry	10,000 pcs
Aluminum profile joint corner (HL6632b/c)	$1.00–10.00/pc	10,000 pcs

The published corner key lines (HL-series, sand-blast aluminum, plastic European type) are suited for UPVC and aluminum profile assembly. The Middle East joint corner is a regularly listed SKU, indicating specific market customization for buyers in the Gulf and North Africa. An OEM-available window latch (5,000 pcs MOQ at $0.40–0.90/pc) rounds out the accessory range for one-stop procurement.

EPDM rubber seal strips

Tianjin Haijinshu Rubber & Plastic Technology Co., Ltd.

Location: Beichen District, Tianjin Platform: Diamond Member, Audited Supplier, Made-in-China.com B2B: hjsseal.en.made-in-china.com

Tianjin Haijinshu is a rubber specialist with over a decade of production experience, covering EPDM seal strips, rubber hoses, PU foam strips, and a range of customized rubber components. Export markets include the United States, Canada, Australia, Malaysia, France, and Italy.5

The window and door seal strip range includes EPDM rubber profiles for aluminum curtain walls (RoHS compliant), T-shape soundproof foam door/window strips, adhesive-backed sponge gaskets, and PU foam-wrapped seal strips. MOQ is 300 meters across most seal strip lines — a low entry point for project-specific cut lengths.

Representative pricing:

Product type	FOB Price	MOQ
EPDM rubber door/window seal (custom, RoHS)	$0.08–0.15/m	300 m
Common rubber seal strips	$0.24–0.34/m	300 m
PU foam seal strips	$0.35–0.55/m	300 m
T-shape soundproof foam EPDM strip	inquiry	300 m

The 300-meter MOQ and RoHS compliance on the aluminum curtain wall seal product are the two distinguishing features versus the high-MOQ pile strip specialists (20,000m+) featured in previous issues. Buyers sourcing small-to-mid volumes or requiring documented RoHS for European projects should shortlist Haijinshu.

Aluminum profile assemblies

Aluminum profile extrusion production line — a typical Foshan factory setup

Aluminum profile extrusion at scale: Foshan factories operate 600–1,800 ton presses with anodizing and powder coating lines in-house

Foshan Pengdong Aluminum Co., Ltd.

Location: Foshan, Guangdong Platform: Verified supplier, own website: profilealum.com; Alibaba presence B2B: profilealum.com/aboutus.html

Established in 2009, Pengdong manufactures 6063-T5/T8 extruded aluminum profiles for sliding windows, casement windows, kitchen cabinets, and roller shutters. Annual revenue is $10M–$50M, with 90–100% export ratio. Core markets are Latin America (Peru, Chile, Bolivia, Colombia — ~55% of sales) and Sub-Saharan Africa (Nigeria, Ghana, South Africa — ~35%).6

Surface treatment options span anodizing (silver, champagne, bronze, golden in matt/gloss/satin), powder coating, wood grain transfer, and polishing. Free mold development is offered against customer CAD drawings. Deep processing (bending, cutting, punching) is available in-house.

Pricing, export, and certification highlights:

Price: From approximately $3.25–3.27/kg for standard handles; architectural window profiles priced on inquiry (typical market range for 6000-series profiles: $3.00–4.50/kg FOB)
Certifications: Multiple certificates listed (images on company website; specific standards not itemized in public profile)
MOQ: Inquiry-based (industry norm for extrusion: 500–1,000 kg per profile shape)
Registered: Foshan (Nanhai/Jihua Road), 10–50 employees

The Latin America specialization (Linea 20, Linea 25, Linea 32 series compatible with Chile, Bolivia, Peru, Ecuador, Argentina standard window systems) is a niche differentiator. Buyers sourcing LatAm-spec profiles — less commonly offered by Africa-focused suppliers — have fewer competitors than the European/Middle East profile market.

Foshan Haofeng Aluminum Co., Ltd. (Guangdong Haofeng Aluminium Industry Co., Ltd.)

Location: Changhongling Industrial Park, Shishan, Nanhai District, Foshan Platform: Made-in-China.com B2B: haofengalu.en.made-in-china.com

Established in 2003, Haofeng is one of Foshan's earlier-generation profile extruders, with 20+ years of accumulated technology and a factory footprint of 30,000 sq m. Six extrusion presses (600–1,800 ton range), one powder coating line, two wood grain transfer lines, and CNC deep processing capacity bring annual production to around 50,000 tonnes.7

Aluminum production equipment at a Foshan-scale extrusion plant — Aluminum extrusion facility: Haofeng runs 6 presses up to 1,800 tons, supporting wide-section and structural profiles 7

Product scope covers window profiles, door profiles, industrial profiles, heat sinks, kitchen cabinet extrusions, and aluminum tube profiles. The company holds patents in powder coating and wood grain transfer processes. Export ratio is 31–40%, with markets in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and the Middle East — with exporting since 2019.

Key commercial details:

Parameter	Detail
FOB price (window profiles)	$3.90–4.60/kg
Min. order	300 kg per profile
Payment	T/T, FOB terms
Lead time (peak season)	6–12 months
Annual output value	$5M–$10M
Certifications	ISO 9001 (stated); patents in coating/wood grain

The $3.90–4.60/kg FOB price is slightly above Pengdong's South America-targeting price band, likely reflecting the deeper processing capability and larger factory infrastructure. The 300 kg MOQ is low by Foshan standards and suits buyers who need multiple custom profile shapes without committing to large per-shape runs.

Sourcing notes for buyers

Rollers: Hanzson's 300-piece OEM entry MOQ suits buyers testing new roller specs without volume risk; 3H INC.'s 40+ year history and CE/TÜV stack better fits buyers submitting to European or North American project compliance files.

Corner keys: Shineright's $0.10–1.00/pc range on standard rollers and aluminum joint corners (HL-series) covers both commodity and semi-custom specs. The 10,000-piece MOQ on corner keys is standard for this product type; buyers needing less should confirm OEM-cut minimums directly.

EPDM seals: Haijinshu's 300-meter MOQ and $0.08/m entry price are among the lowest published figures in this category — suited for project-lot sourcing rather than continuous production replenishment. RoHS documentation is available for the curtain wall EPDM product line.

Profiles: Pengdong's Latin America profile series (Linea 20/25/32) fills a gap underserved by most Africa- and Europe-oriented Foshan factories. Haofeng's larger press fleet (up to 1,800 tons) supports wider and heavier section profiles at the same 300 kg MOQ.
