Describe the greenhouse environment
Steel greenhouse components can encounter humidity, condensation and substances associated with the application. Selecting galvanized steel requires more than naming the product. Describe the location, irrigation arrangements and expected contact conditions in the technical file. This allows the coating approach to be assessed against actual use.
Connections and cut surfaces
Determine how tubes, sections and connectors will be assembled before fabrication. If drilling, cutting or welding is planned after coating, assess protection of the affected areas separately. Show galvanizing openings for hollow sections in drawings. Section selection and load calculations remain engineering requirements: galvanizing alone does not establish structural suitability.
Delivery and service planning
Store components without trapping moisture before assembly. Observe water or dirt accumulation at connections and record coating damage. Include greenhouse drawings and service conditions with the component list when requesting a quotation. Review the relevant application on Galmetsan’s greenhouse materials page and discuss galvanizing requirements with the technical team.
Assessing existing and new components together
A greenhouse extension may connect new galvanized parts to existing members. Ordering new parts without knowing the condition, dimensions and connections of existing material can create incompatibilities. Relate existing component information to new drawings in the technical file. Identify any site drilling or cutting, and assess connection materials and potential water retention. The responsible project team assesses structural suitability; galvanizing discussions clarify the associated surface protection scope.
