In this article, we’re going to clarify what lead codes are, and which code is best for certain types of roofing applications.
What are lead codes?
The thickness – and therefore the weight – of lead will need to be carefully selected depending on the application. Lead roofing structures can fail if you have miscalculated or ignored the correct lead codes, and to help maintain high standards in the industry, rolled lead is manufactured to meet BS EN 12588 guidelines.
That means rolled lead will fall under one of six lead codes, ensuring project coordinators can select lead roofing materials of the appropriate weight for their requirements.
Reputable lead supplier
To ensure your lead roofing project is completed without any short or long term issues, it’s essential that you consult and use a reputable lead roofing supplier for the job.
This ensures that, whatever the application and whatever the scale of your lead roofing work, you will receive the appropriate lead code material, manufactured to the highest possible standards specific to your needs.
