Installation of Warehouse Racking & Steel Structures
Engineering precision, strict schedule discipline, and compliance with EN 15635. Subcontracting installation partner for industrial & logistics facilities.
Independent Subcontractor for Industrial Storage Systems
KETARSIS Sp. z o.o. is a specialized installation subcontractor supporting general contractors, racking manufacturers, 3PL providers, and e-commerce leaders.
Modern logistics hubs require flawless assembly of steel structures reaching up to several dozen meters high. Plumb line tolerances down to millimeters determine the safety of entire facilities and smooth operation of VNA trucks and shuttles. Our crews eliminate risk via digital laser alignments, level verifications, and calibrated torque fastening.
Storage Systems We Install
Professional installation across all market-leading pallet and small-parts storage designs:
Standard Pallet Racks (APR)
Standard and high-bay configurations up to 15 m. Assembly of upright frames, load beams with locking pins, vertical/horizontal bracing, and safety add-ons.
Drive-In & Drive-Through Racks
High-density block storage for uniform SKU volume (cold storage, FMCG). Accurate rail alignment guarantees smooth forklift maneuvering.
Warehouse Mezzanines & Platforms
Multi-tier steel platforms multiplying available floor space. Installation of WEMA decking, kickplate handrails, stairs, and tilting safety gates.
Cantilever Racking
Specialized cantilever systems engineered for long loads: steel bars, pipes, timber planks, and oversized bulky inventory.
Shelving & E-Commerce Picking
Modular small parts shelving for fulfilment centers. Wire mesh, steel shelves, vertical dividers, and ergonomic hand-picking aisles.
Impact Protectors & Safety Barriers
Installation of upright column guards, rack-end barrier rails, anti-collapse back mesh nets in pedestrian zones and loading bays.
Structural Integrity & EN 15635 Standards
All installations strictly follow European EN 15635 standards. We supply exhaustive as-built paperwork and critical parameter checklists:
Laser Leveling & Plumb Control
Verification of slab levels via laser optics. Fine leveling of upright baseplates with steel shims to strict plumb tolerance.
Certified Concrete Anchoring
Installation of certified mechanical expansion bolts or chemical resin studs adhering to design embedment depth and shear values.
Calibrated Torque Verification
Tightening of frame joints and diagonal bracings with calibrated torque wrenches to guarantee full structural rigidity.
Load Capacity Plates & Safety Pins
Systematic check of all beam safety retention locks and mounting clear, durable maximum bay capacity plates.
Frequently Asked Questions (FAQ)
Practical answers regarding our warehouse racking assembly operations:
Which technical standards govern warehouse racking installation in the EU?
The primary standard is EN 15635, coupled with companion norms EN 15512 and EN 15620. They govern verticality tolerances, element load ratings, slab requirements, and strict commissioning protocols.
Do Ketarsis assembly crews hold certified equipment licenses and HSE training?
Yes. All operatives hold verified aerial work platform (scissor and boom lifts) and forklift operator licenses, medical work-at-height fitness certifications, and strict HSE training.
Do you install racking materials supplied by the client or manufacturer?
Yes, we operate in pure assembly subcontracting format (labor only). We assemble systems supplied by racking manufacturers, general contractors, or warehouse owners, providing all our own tools and logistics.
What is the typical timeframe for installing a standard pallet warehouse?
Installation pace depends on upright height and slab clearance. On average, a synchronized 6-person Ketarsis team erects between 350 and 600 pallet positions per workday on standard APR racks.
Do you handle racking dismantlement and annual safety audits?
Yes, we perform complete warehouse racking dismantlement with parts cataloging and transport packing, as well as periodical structural safety inspections conforming to EN 15635.
