Components of M7 heavy duty steel racks

As a heavy-duty rack manufacturer, Mecalux makes its M7 heavy duty racks and all other storage solutions from top-quality materials for increased reliability and safety.

The basic structure of M7 racks consists of frames, beams and shelves. These parts provide the storage system with the robustness and stability needed to multiple heavy and unwieldy loads.

The shelves constitute the flat surfaces that support goods on the various storage levels. Shelves can be placed on beams or supports and come in different materials and finishes.

M7 heavy duty racks include numerous safety features (some standard, others optional). They ensure the storage system’s stability and help prevent accidents that could affect operators or the goods stored.

Frames consist of uprights and diagonal braces

Frames

Vertical elements comprising two uprights connected by diagonal bracing, onto which the beams are fitted.

Beams are horizontal elements used to support the shelves and stiffen the racking system

Beams

Horizontal elements that support the shelves. Beams are joined to the uprights by connectors or clips. There are two types of beams: stamped and welded.

Uprights are anchored to the floor by frame footplates

Frame footplates

Frames are fixed to the floor via footplates, which are fitted to the base of the uprights. Different types of frame footplates are available depending on the upright model.

Shims are used for racks installed on irregular floor surfaces

Shims (levelling plates)

Elements used to level racks installed on an irregular floor surface. Different shims are available for each upright model. They have different thicknesses for greater levelling precision.

Anchor bolts secure M7 heavy duty racks to the floor

Anchor bolts

Components that secure the frame uprights to the floor. Anchor bolts vary depending on the strain the racking must bear and the characteristics of the floor.

Frame unions reinforce the stability of double-sided racking

Frame unions

Steel parts used to join double-sided racks, giving them greater cross-aisle stability.

Frame splices connect two uprights vertically

Frame splices

Elements that join two uprights vertically. They are used when single-piece frame uprights cannot span the entire height of the storage system.

Portal ties ensure the transverse stability of high-bay racking

Portal ties

Parts used to connect the top of the racking units when their height calls for superior cross-aisle stability. Portal ties are installed when the height is seven times greater than the depth.

Galvanised shelves sit on the racking beams

Galvanised shelves

These rest on the beams. Each level contains several shelves of varying widths depending on the length of the level and the weight of the load to be stored.

Chipboard shelves can incorporate a cross-tie to enhance their load capacity

Chipboard shelves

These are fitted between the beams. Their thickness and dimensions are tailored to the type of load each level must bear.

Double-deep chipboard shelving is used in very deep levels

Double-deep chipboard shelving

Shelves consisting of a single chipboard panel for very deep levels. The structure is reinforced by two beams placed in the centre.

Mesh shelves are rectangular electro-welded metal grids that rest on the beams

Mesh shelves

Rectangular metal grids welded onto cross-ties. They rest on the beams and facilitate the ventilation of the stored goods and water flow if the fire safety system is activated.

HM shelves are made of single-piece galvanised sheet metal

HM shelves

Made of single-piece galvanised sheet metal, these are used in levels comprising only shelves and supports (without beams).

Safety pins prevent beams from dislodging accidentally

Safety pins

Metal parts inserted into the corresponding slot of each beam connector to prevent accidental displacement.

Side and rear mesh enclose the racks for increased safety

Side and rear mesh

Mesh panels that enclose the racks. They protect the stored goods and prevent products from falling or mixing with those on other levels.

Chipboard side panels provide the racking with an attractive finish

Chipboard side panels

Panels that prevent stored merchandise from falling or mixing with products on other levels. They provide the racks with an attractive finish.

Los atirantados verticales se colocan en las M7 con paneles HM para reforzar su estabilidad

Vertical cross bracing

Tubular profiles with specially shaped ends. These braces are installed in racks with HM shelves to ensure down-aisle stability.

HD beams enhance the stiffness and stability of high-bay racking with HM shelves

HD beams

Components used to strengthen the stiffness and down-aisle stability of high-bay racking with HM shelves (without beams). These beams can also be used to increase the load capacity of the shelves.

Safe load warning notices identify the technical characteristics of M7 heavy duty racks

Safe load warning notices

Signs detailing the storage system’s technical characteristics (maximum weight, height, etc.). These signage plates are placed in clearly visible areas on the ends of the racks.
