How to Compare Ductile Iron Covers and Frames Price for a Secure Access Point

Fix the opening and frame combination

The 600 mm clear opening defines the access space through the round assembly. Measure the existing opening and the seating area, then compare them with the 640 mm cover and 850 mm frame. The 100 mm height matters where the frame must meet a prepared concrete or paved surface.

This assembly suits replacement work at a round access point that matches these dimensions. Include the clear opening, cover diameter, frame diameter and height in the request so each quotation describes the same physical arrangement. A different opening or a square access point calls for a drawing and measured seating dimensions before we can assess the fit.

The 65 kg unit weight should shape the handling plan. Picture the assembly arriving near a road opening: the route from the receiving area to the work location needs to accommodate the complete unit. Plan how the frame and cover will be moved before ordering several pieces, and include the quantity so the receiving team can prepare for the shipment.

Match EN124 D400 to the location

Our cover and frame have an EN124 D400 loading class. Choose this configuration when the project design calls for that class, then relate the requirement to the actual position of the access point. A trafficked paved area and a restricted site access point may have different design requirements, so provide the location and required class with the inquiry.

The phrase “ductile iron covers and frames price” does not define a loading requirement. Compare offers only when the opening, frame, cover, height and loading class are aligned. Otherwise, a lower figure may describe a different assembly and cannot support a useful purchasing decision.

Decide how access will be controlled

Two anti-theft locking devices form the safety system. This arrangement suits an access point where unauthorized opening is a procurement concern and maintenance access must remain controlled.

The lock affects the site routine. An authorized person needs the special key during planned maintenance, and the cover must be secured again after the work. Put the safety system in the purchase request instead of asking for a general “lockable” cover. That wording keeps the requested configuration clear when prices are compared.

Specify the lid support and coating

An elastomer PP support is attached to the edge of the frame to support the lid. It suits access points where lid contact with the frame, movement and noise are part of the selection discussion.

The coating is black asphalt, also called bituminous paint. Name the coating with the dimensions and loading class in the quotation request. The result is a defined assembly for comparison, with the surface finish included as a purchasing condition.

Build a comparable price request

Ask for the complete round cover and frame with the safety system. Your request should identify:

• 600 mm clear opening;
• 640 mm cover diameter and 850 mm frame diameter;
• 100 mm height;
• EN124 D400 loading class;
• black asphalt or bituminous paint;
• double anti-theft locking arrangement;
• quantity and delivery location.

Quantity belongs in the request because it affects the receiving plan. Delivery location also gives us the information needed to prepare a quotation around the intended shipment. If your project uses client-specific shipping marks, include those requirements with the quantity and location.

Questions to settle before requesting a quotation

Send the site details with the price request

Choose this Ductile Iron Manhole Cover and Frame With Safety System for a round access point requiring a 600 mm clear opening, 850 mm frame, EN124 D400 loading class and controlled access through two locks. Send us the opening drawing, seating dimensions, surface or traffic location, quantity, delivery location and shipping-mark requirements so we can prepare a comparable quotation.
