Enquiries and drawings
The enquiry form collects the contact and project information you choose to provide, together with attached files. It is used to assess your request and communicate with you about the project. A confirmed submission is stored in a private enquiry area accessible to authorised site operators.
Confidential information
Share only documents you are authorised to disclose. If your project requires a confidentiality agreement, contact us before uploading drawings. Submission of a form does not itself create an NDA.
Optional analytics and advertising
You may accept or decline optional analytics and advertising measurement through Cookie settings. Where configured, these tools may use campaign identifiers and page interactions to understand visits and enquiries. Optional tags are blocked until you allow them. Contact details, drawing content and project descriptions are not sent to analytics or advertising tags by this website.
Storage and controls
The website stores your cookie preference. With optional measurement enabled, campaign attribution may be stored for your browser session. Changing your preference to Essential only clears the website’s optional attribution storage and stops further optional tag loading. Third-party cookies already set may also be cleared in your browser settings.
Server operation
Enquiry data and attachments are stored on the website server. Access is restricted to authorised operators. Hosting services may process basic connection data to deliver and protect the website. Drawings are not published as website content.
