Import Tips
• Specify corrosion resistance metrics in technical specs to differentiate from structural E-glass
• Ensure sizing compatibility declaration matches intended resin systems for end-use verification
• Package on stable beams to prevent roving tension loss; damaged packages risk strand breakage claims
