JTT 737-2009 Filled Epoxy-Coated Steel Strand

Standard Overview

JT/T 737-2009 Filled epoxy-coated steel strand is a transportation industry standard of the People's Republic of China. It specifies the product classification, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of filled epoxy-coated seven-wire steel strand.

Why It Matters for Flexible PV Brackets

• Filled epoxy coating completely fills the interstices of the seven-wire strand, giving excellent sealing against moisture and corrosive media.
• It is the key strand type for flexible brackets in high-rainfall, coastal and offshore environments, where service life of more than 30 years can be expected.
• Its mechanical and coating acceptance criteria support the material selection and quality acceptance of flexible bracket cable systems.
