Submitting Drawings and Specs for Metal Fabrication Estimates

t502-40

To get an accurate metal fabrication estimate, submit scaled drawings, clear elevations, and a written specification covering materials, finishes and site conditions. Include photos and mark which dimensions were measured on site and which come from design files. The more complete the package, the fewer revisions before production starts.

What to Include in Your Submission

A useful package starts with the drawings themselves. Send plans, elevations and sections at a known scale, with dimensions clearly labeled. Show the opening sizes, wall thicknesses and the position of each metal element relative to finished floor levels.

Scaled PDF or DWG files for each relevant elevation
Detail drawings for railings, gates or structural connections
Photos of the existing site, especially where work meets masonry
A short written specification listing materials and finishes

Label every drawing with its revision date so we always work from the latest version.

Measuring on Site: When Drawings Are Not Enough

Drawings often differ from the built condition, particularly in older buildings or renovations. For window bars, gates, balcony railings and stair work, an on-site measurement is usually required before production. Our team takes measurements, checks plumb and level, and notes any obstacles such as electrical boxes, drainage or uneven slabs.

If you have already measured, indicate which dimensions are verified and which are taken from design files, so we can flag anything that needs a second check.

Drawing, Specification and Client Approval

After reviewing your files and measurements, we prepare a fabrication drawing and a written specification. This document describes profiles, connections, anchoring method, finishes and tolerances. Please review it carefully and confirm in writing before production begins, since changes after approval are costly for everyone.

Where the design affects safety, such as railing heights or infill spacing, the requirements of the Israeli railing standard SI 1142 apply. Exact values should be confirmed with your structural or safety engineer rather than assumed.

Materials and Finishes to Specify Early

Specify materials and finishes at the estimate stage, because they change both the scope and the production sequence. Iron, aluminum and stainless steel each behave differently in fabrication and on site. Galvanizing and powder coating require planning for handling and transport.

Material grade and profile type
Hot-dip galvanizing or powder coating, with RAL or colour reference
Glass type and thickness for glass railings or partitions
Any stainless steel finish such as brushed or polished

From Approval to Factory Production

Once approved, the job moves into our factory at Rival Street 37 in Tel Aviv. Cutting, welding, assembly and quality checks take place in-house, which allows us to keep close control over dimensions. Finished work goes to finishing, whether galvanizing or powder coating, before it is packed for delivery.

Let us know early if there is a fixed installation date, so production can be scheduled around it.

Installation and Handover Coordination

Installation is coordinated with your site schedule and the general contractor. Anchor locations, embedded plates and openings should be ready before our crew arrives. Where possible, we agree on an inspection walk-through at handover to confirm alignment, fixings and finish condition.

Clear communication between the architect, the contractor and our team prevents most installation delays.

Frequently asked questions

What file formats do you accept for drawings?

We accept PDF and DWG files at scale, along with clear photos of the existing site. If you send sketches, please include dimensions and scale information.

Do you measure on site before giving an estimate?

For most custom work such as railings, gates and window bars, on-site measurement is recommended. It confirms the real conditions behind the drawings.

Who approves the final fabrication drawing?

The architect or designer normally gives final approval, after reviewing our fabrication drawing and written specification. Production starts only after written confirmation.

Can you work from partial drawings or a rough sketch?

Yes, but the estimate will be based on assumptions that need checking. Please mark any uncertain dimensions so they can be verified on site.

Common mistakes to avoid

Sending drawings without a scale or revision date, and assuming site dimensions match the plans, are the most common causes of rework. Late changes to finishes after production has started also cause avoidable delays.

Our recommendation

Send one consolidated package with the latest revision, a written specification and site photos, and confirm the finish and anchoring method early. This single step usually shortens the path from estimate to installation.

Summary

A complete package of scaled drawings, verified measurements and a clear specification leads to accurate estimates and smoother production and installation.
