a Values do not apply for structural bolting.
b For structural bolting d W M12.
c Nominal values are specified only for the purpose of the designation system for property classes.See Clause 5.
d In cases where the lower yield strength ReL cannot be determined, it is permissible to measure the stress at 0,2 % non-proportional elongation Rp0,2.
e For the property classes 4.8, 5.8 and 6.8 the values for Rpf min are under investigation. The present values are given for calculation of the proof stress ratio only. They are not test values.
f Proof loads are specified in Tables 5 and 7.
g Hardness determined at the end of a fastener shall be 250 HV, 238 HB or 99,5 HRB maximum.
h Surface hardness shall not be more than 30 Vickers points above the measured core hardness of the fastener when determination of both surface hardness and core hardness are carried out with HV 0,3.
i Any increase in hardness at the surface which indicates that the surface hardness exceeds 390 HV is not acceptable.
j Any increase in hardness at the surface which indicates that the surface hardness exceeds 435 HV is not acceptable.
k Values are determined at a test temperature of −20 °C, see 9.14.
l Applies to d W 16 mm. m Value for KV is under investigation.
n Instead of ISO 6157-1, ISO 6157-3 may apply by agreement between the manufacturer and the purchaser.
 
 

 

 

 

 

Applications
 

⚫ Commercial and residential buildings
⚫ Marine applications and remote areas
Features
⚫ Anodized 6005-T6 aluminum extrusion
⚫ Innovated designed of the Tilt-in modules, which can be pre-assembly with the clamp, make the
installation easy and quick.
⚫ Suitable for difference conditions and the most solar panels at present market.
⚫ Significantly higher strength-to-weight ratio than other framing products, providing improved
efficiency due to greater frame spans, inherent corrosion resistance resulting in low ongoing
maintenance and an extended product life.
⚫ 10 years limited warranty backed up by QBH company
