Guide to metal structures in Menorca: planning, design and assembly without surprises

If you want a metal structure to work well for years, success is not in “fast welding”, but in plan correctly before manufacturing.

In Menorca this is even more important for three reasons:

1. marine environment (corrosion),
2. wind exposure,
3. work with access and logistics sometimes limited.

1) Defines actual use (not just form)

Before design, it is appropriate to fix:

• what function it performs (cover, loft, technical support, pergola, gangway, reinforcement),
• what loads you will have (persons, equipment, wind, enclosures, maintenance),
• what service life you expect and how much maintenance you accept.

When use is clear, the type of profile, supports and finishes are best chosen.

2) Lifting and measuring: critical phase

The most expensive errors arise in measurement. Therefore, in professional workshop work is done with:

• measurement of gaps and actual elevations,
• verification of squads and anchor points,
• interference detection (installations, drains, carpentry).

A good uprising avoids impromptu cuts in construction and delays for pieces that do not fit.

3) Material selection and anti-corrosion system

In the coastal environment, it is not enough with “painted steel”. The usual strategy combines:

• structural steel suitable for the project,
• surface preparation,
• protection system (printing + finishing), or
• galvanized/inox when applied by exposure and use.

The key is to adjust the system to the real environment: inside, outside protected or outdoor exposed to saline breeze.

4) Design of joints and assembly from the start

Many incidents come because they do not think of the assembly in phase of design. It is necessary to solve before:

• if the joint is welded, screwed or mixed,
• hoisting sequence and positioning,
• tolerances for manufacturing and absorption of deviations,
• accessibility for screwing, checking or maintaining.

Designing “to manufacture and assemble” reduces work hours and rework.

5) Coordination with work and permits

Depending on the scope of the project, coordination with optional direction or specific technical documentation may be necessary. Even in small works, it is advisable to validate:

• compatibility with enclosures and slopes,
• drainage and water disposal,
• use security and maintenance accesses.

6) Quick checklist before moving to workshop

Before launching production, check this minimum:

• use and defined loads,
• verified measures in the field,
• confirmed material and finish,
• joints and anchors resolved,
• validated mounting sequence,
• production times + coordinated assembly.

Relationship with calculation, CAD and workshop process

Conclusion

The well-executed metal structure starts long before cutting: it begins in the technical definition. If the objective is to avoid surprises, it is advisable to work with complete flow: lifting, design, manufacturing and coordinated assembly.
