- EMMA regime (Las Mañanitas plant): machinery, raw material and inputs imported into the plant duty-free, plus optimized Caribbean logistics.
Demand for prefabricated warehouses in Panama is growing with logistics activity in the Colón Free Zone (ZLC), industrial parks in the interior provinces, and e-commerce. Companies want predictable schedules, less on-site labor, and construction that does not interrupt existing operations. PEB Corp engineers prefabricated steel warehouses to the Structural Design Code for the Republic of Panama (REP-2021), drawing on more than 350 PEB Corp Group projects. The ISO 45001 (occupational health and safety) and ISO 9001 (quality) certifications belong to the PEB Corp Group and cover its management systems.
If you are evaluating a warehouse or building of this type, turnkey execution is carried out by SmartBrix Construction (industrial sector), with PEB Corp engineering and steel from the group plant. Reference prices, local codes, and export logistics for this market are on our Panama page.
Standard sizes and configurations
PEB's modular prefab warehouses range from 500 m² (5,382 ft²) to 5,000 m² (53,820 ft²), covering virtually all market demand. Most-requested sizes in the region are 1,000 m² (10,764 ft²), 1,500 m² (16,146 ft²), 2,500 m² (26,910 ft²), and 3,500 m² (37,674 ft²). Each module is architected for flexibility: lateral bays (extensions 20–40 m / 66–131 ft wide), mezzanines for office/storage above, and canopy extensions for loading zones—all executable without halting existing operations.
PEB's modularity allows configuration to specific needs. A 500 m² warehouse for small retail typically measures 20 m × 25 m (66 ft × 82 ft) with 6 m (20 ft) clear height. A 2,500 m² logistics facility might be 40 m × 62.5 m (131 ft × 205 ft) at 7.5 m (25 ft) height. Heights range 5.5 m (18 ft, low-profile storage) to 10+ m (33+ ft, racking systems).
Cost table by size and floor system
2026 PEB Corp Group reference for the Zn-Al-Mg 275 g/m² steel structure (steel structure only, MEP and civil works not included; Panama 2026 reference):
500 m²: 220–260 USD/m²
2,000 m²: 180–220 USD/m²
5,000 m²: 150–180 USD/m²
Foundations, floor system, cladding and MEP: quoted per project.
The reference covers the Zn-Al-Mg 275 g/m² steel frame (ZM275 / ZMM275). Foundations (1.5 m / 5 ft typical depth, steel anchor rods), the concrete slab (200 mm / 8 in thick, reinforced mesh) and entry systems are quoted per project. Fabrication lead time is confirmed against each order and erection time depends on size; overall, the schedule is shorter than traditional cast-in-place construction.
Floor system options and finishes
Standard concrete (20 cm / 8 in, fc 4,000 psi) is most economical and adaptable for generic warehousing. Polished concrete (hardener additives + polymer sealer) costs more but resists forklift traffic better, reduces dust, and eases cleaning. Epoxy (2-component system, 3–4 mm / 0.12–0.16 in thick) is premium: it costs considerably more than concrete but offers exceptional chemical resistance—ideal for chemical, lubricant, or food warehouses.
Foundation per REP-2021: in competent soils (typical Panama clay/sand) uses isolated footings or slab-on-grade, 1.2–1.8 m (4–6 ft) depth. In weak soils or high water table, concrete piles (0.40 m × 0.40 m / 16 in × 16 in, length 6–10 m / 20–33 ft). Foundation cost depends on soil bearing capacity; geotechnical study mandatory.
Roof and thermal insulation systems
PEB prefabs offer multiple roof options. Standard galvanized metal (16–18 gauge) is economy baseline, minimal insulation. For tropical thermal load, EIFS (External Insulation Finish System) recommended: 100 mm (4 in) expanded polystyrene (R-value 3.85) + acrylic finish, quoted as an add-on. Alternative: 75 mm (3 in) polyisocyanurate (R-value 4.5) + reflective membrane—pricier but superior in coastal/humid zones.
Thermal control is critical in Panama. Uninsulated warehouses in Coclé or Los Santos regions reach 45–50 °C (113–122 °F) internally at peak hours—unacceptable for temperature-sensitive cargo. EIFS at 100 mm markedly reduces heat gain through the roof. Forced ventilation (auto dampers, electric exhaust fans) is quoted as an add-on but is often necessary for relative humidity control in storage operations.
Integrated MEP systems: electrical, plumbing, and mechanical
Prefab warehouses include BIM-designed MEP infrastructure before fabrication. Electrical: 150–200 A service panels, coordinated with the local utility. Galvanized conduit for circuit distribution (120/240 V), 4–6 load centers for operational clarity. LED lighting (low-consumption, 10–15 W/m²), typically 200–400 lux for general operations.
Water: PVC potable lines (0.5–1 in / 13–25 mm to faucet points in offices/wash areas; minimum 2–3 points per warehouse >1,500 m²). Wastewater: drain piping to septic tank or municipal connection if available. Storm drainage: galvanized gutters + PVC downspouts with sumps. Integrated MEP budget: quoted per project depending on complexity.
Roll-up door specifications and sizing
Warehouses require minimum 2–3 loading access points. Standard roll-up steel doors: rigid-frame, aluminum or steel slats, automatic motor with obstruction sensor. Common sizes: 3.5 m × 4 m (11.5 ft × 13 ft, personnel + small forklift), 4.5 m × 4.5 m (14.8 ft × 14.8 ft, dual operation), 6 m × 5 m (19.7 ft × 16.4 ft, heavy load). Opening speed: 0.3–0.4 m/s. Cost per unit depends on size and motor type. A 2,500 m² typical warehouse incorporates 2 large roll-ups (north + south facade) + 1 aluminum/glass personnel door.
Delivery timeline by warehouse size
The schedule is confirmed per project and grows with warehouse size. It covers the soil study, structural design per REP-2021, CNC fabrication, transport, and on-site erection; fabrication lead time for each order is confirmed against the order.
Colón Free Zone (ZLC) logistics advantage
Prefab warehouses in Panama gain a clear logistics advantage in the ZLC. In a zone where operational speed is critical, traditional construction underperforms prefab: the structure is fabricated in the plant while civil works advance. The shorter timeline lets merchandise enter the zone sooner and cash flow start earlier.
Additionally, steel prefab enables modular expansion. A company starting 1,000 m² can add 500 m² laterally next year without demolition or operational halt. This incremental growth model suits expansion-phase enterprises, especially in Colombia where logistics boom is sustained.
Prefab vs. traditional construction
Traditional (masonry/concrete) in Panama: longer schedules, labor-intensive daily work on site, climate and design-change risks, tolerances ±5 cm (2 in). Cost: quoted per project, and changes or delays tend to add overruns.
Prefab steel (PEB Corp engineering, erection by SmartBrix Construction): shorter schedule, fewer workers on site, and a ±0.5 mm (±0.02 in) CNC fabrication tolerance. Steel structure: reference 180–220 USD/m² for 2,000 m² (steel structure only, MEP and civil works not included; Panama 2026 reference). ROI: for a rental warehouse, each month of earlier delivery is one more month of operating revenue.
How a prefab warehouse in Panama is defined
Every warehouse is defined with the same data: floor area and clear height, operating loads (racking, forklifts, bridge crane), floor type, number of loading doors, location and target schedule. With that information, PEB Corp develops the engineering and the technical proposal; turnkey execution is carried out by SmartBrix Construction.
