Top 10 Solar Frame Extruders in China (2026)

Entries are drawn from SAMR business registry data cross-referenced with official-site product listings (product name matched against 'solar' / 'photovoltaic' / 'PV' patterns); no paid placement and no third-party 'Verified' claim is made. Score blends category focus (40 pts: share of a supplier's verified catalogue that is solar/PV-frame profile, log-adjusted so a single-product supplier cannot outrank a supplier with deeper solar-frame evidence), export readiness (30 pts: English-language official site + additional language sites), and registered scale (30 pts: registered capital and years since founding, each percentile-ranked against the qualifying supplier pool). Missing fields score 0 on that dimension -- they are never inferred or treated as a negative signal. External-authority points (max 20) come only from verifiable public sources, each cited with its source URL; secondary-source reports earn half weight, unverifiable leads none. Absence of external signals is not penalized.
